Difference between NF and USP Grade?
In order to successfully manage any industry, standards must be in place for products to be compared against. In the case of the chemical industry, there are two primary standards commonly known as USP Grade and NF Grade.
The two organizations, National Formulary (NF) and the United States Pharmacopeia (USP) provide the standards for drugs, dosages, chemicals, preparations, and so on. This information is updated every year and published in a joint compendium, known as USP-NF.
Both organizations include standards for chemical grades, but there are differences between the two – not everything that the USP recognizes is recognized by the NF, and vice versa.
In order for a product to have an NF Grade, the product must meet all of the requirements as per the NF monograph (single study) for that particular product. If no study has been made for that product by the NF, the product cannot be labeled as NF Grade.
In order for a product to have a USP Grade, the product must meet the requirements as per the USP monograph. Again, if no study has been made for that product by the USP, the product cannot be labeled as USP Grade.
In either case, the products are regulated by the Food and Drug Administration, and can be used in pharmaceutical processing, prescription compounding, and for use in food processing operations.
Exclusion from the USP-NF does not necessarily indicate that a product is unsuitable for any purpose, only that enough research has not yet been conducted to confirm its suitability and safety. However, for assurance of safety and suitability, it is recommended to use products that do have USP-NF grades.
A Brief History
Originally, NF and USP were entirely separate entities, but merged together in the 1970s. Since then an effort has been made to combine all the research made under one name – hence USP-NF Reference Standards.
The idea is to gradually phase out the use of NF completely. In due course, all NF Reference Standards will become USP Reference Standards.
For all intents and purposes, if a product is labelled as complying with NF, USP, or USP-NF standards, you can be assured of its suitability for purpose, and of its quality.
To further add to its importance and comprehensiveness, the USP acquired the Food Chemicals Codex (FCC) in 2006, a compendium of internationally recognized standards for the purity and identity of food ingredients. The data from this compendium is now included within the USP-NF publication.

What is PEG 400, Polyethylene Glycol 400
PEG 400 is an abbreviation of polyethylene glycol 400, and is a colorless viscous liquid. It has many applications due to its low toxicity, and it is soluble in water, alcohols, glycerin, among other liquids.
The FDA classes it as “Generally Regarded as Safe” meaning that it is safe to use as a food additive or base. It is toxic in very high doses, but the amounts used in the food industry are minimal and safe for human consumption.
PEG 400 can be used as a sweetener, and as a carrier for flavor, including in vaping products as a carrier for flavor, with or without tobacco. The boiling point of PEG 400 is higher than many MCT oils, making it a relatively safe chemical to be used in the vaping industry.
Within the pharmaceutical industry, PEG 400 is used as a solvent, plasticizer, and a surfactant to lower the surface tension of water. It is also used as an ointment and suppository base, along with being a lubricant for tablets and capsules making them easier for patients to swallow.
PEG 400 is also used in toothpaste, and as an ink solvent in certain desktop printers.
With so many uses, it is easy to confuse PEG 400 with a regular food product – it’s not, it is used with foodstuffs to change their properties. Consuming food with PEG 400 contained within it is not the same as consuming printer ink, in the same way that consuming a cake is not the same as eating an egg. While one of the ingredients is the same, the end product is vastly different.
What does “400” mean?
The number 400 is a reference to the average molecular weight of the PEG. In the case of PEG 400, the molecular weight is 400 unified atomic mass units (or “daltons”), allowing the composure of the compound to be known. A weight of 400 daltons is equivalent to a chain of around 9 ether repetitions within the molecule.
Longer chains weigh more, shorter chains weigh less, and the number given after the PEG designation reflects this.
Differences in molecular weight affect the viscosity of PEG, leading to different weights being used in different products and circumstances. However, no matter the weight, the general properties of PEG remain the same.
Is it used in antifreeze?
No, polyethylene glycol is not used in antifreeze – ethylene glycol is, and has different properties to PEG 400. Ethylene glycol is not suitable for consumption.
We offer Polyethylene glycol 400, PEG 400 in many different grades and packaging sizes. For pricing and to see how you can save money on your PEG 400 please do not hesitate to request pricing today.
What is HPLC Grade Acetonitrile?
It is perhaps one of the most common solvents used in the laboratory today, HPLC Grade Acetonitrile. The term HPLC stands for high performance liquid chromatography. HPLC is an analytical chemistry technique that forces a sample with pressure and pumps through a column filled with absorbent material. As the material passes through the common different flow rates occur when different materials are absorbed into the column at different rates leading to separation. This separation is then measured and compared with known results to identify your sample.
Now that we know what HPLC stands for why do we use HPLC grade? The term grade stands for the purity and cleanliness of a solvent. When performing HPLC testing you want to know exactly what’s in the solvent to avoid contamination and incorrect identification of samples. This is why only high purity HPLC grade acetonitrile can be used. If another grade such as ACS grade acetonitrile was used your sample would contaminants and peaks and valleys all over the place giving you a false identification. It is imperative that your solvents are not only clean but also reliable. That is why RightPath Industries created highpuritysolvents.com, an online web store allowing you to purchase HPLC grade acetonitrile at a fair price quickly and easily.
This is why we offer HPLC grade acetonitrile to our analytical and laboratory customers to ensure that each and every time you get consistent and reliable results.

Caution with Chemicals in the Workplace
When working in any industry where a serious accident could occur on the job, safety is absolutely paramount. This is especially true if your line of work finds you in a laboratory working with dangerous and/or sensitive materials such as chemicals. However, not all laboratories or lab managers are as thorough with safety training as is needed, and some researchers may not be as attentive as they should be during training. Nevertheless, safety remains a top concern for those working in these particular fields, so we’ve gathered some data on the industries that see the most injuries and have put together some tips to always keep in mind when working with hazardous chemicals in the workplace.
Coal Comeback? Coal Testing Outlook and Opportunities
Is the comeback of coal on the horizon. As many of you have seen President Trump is working on repealing some of the clean air act laws that lowered the emission rates of CO2 which mainly effected coal fired power plants. As many of you may also know the large coal and energy companies in the United States do not have the capabilities to test many of their coals in house. This is where specialty laboratories perform in house testing of coal samples and provide those analysis back to the companies requesting testing. Some of these tests such as the sink and float analysis are tried and true methods that have been used for the past 50 years to analyze coals. Two of the main materials used in sink and float analsysis are dibromomethane and perchlorethylene. These are both what are termed as halogenated solvents and are both very dangerous to work with and have been known to cause cancer. This is one reason why RightPath Industries makes all of our customers using halogenated solvents require the filling out of a user agreement form to ensure that staff is properly trained in how to handle the materials.
The main reason for the slow demise of coal over the past few years can be viewed as two fold. One being the clean air act which caused a significant disruption with competitive energy companies in having to provide new scrubbers to be below the new EPA limits. The second and perhaps the main reason is rise of fractal drilling and the marcellus shale gas reserve. Coal testing laboratories are also feeling the burden of lowered coal usages. There has been a reduction at coal testing labs by over 70% in the past 3 years. Many coal testing labs have since gone out of business due to the low sample request by energy companies.
As you can see in the above figure in 2012 Natural gas in 2012 became the predominant source of energy for the United States surpassing coal. This is mainly due to the large natural reserves and lower costs associated with extraction of coal from the earth utilizing techniques such as fractal drilling which drive the cost down considerably when in comparison with coal.
We believe that while the clean air act redaction might help in the short term for some coal fired power plants overall due to the large and cheap supply of natural gas moving forward coal production and with it ancillary markets and employment in the coal sector will continue to suffer.
As many of our customers in coal country there are still opportunities utilizing current infrastructure in many of the laboratories across the country. Many coal labs already contain the required staffing as well as testing equipment needed to begin operations in environmental as well as analytical testing services. If you are looking to make the switch please feel free to contact RightPath Industries and see how our team of experts my be able to help you.
