Application Notes

Using Full Evaporation Technique (FET) to analyze the solvent residual (California Residual Solvents Category I and II) in cannabis oil by a CDS dynamic headspace module

Solid-phase extraction (SPE) is a powerful technique for LC­–MS analysis. SPE offers benefits for various solutes from a wide range of samples. Modern SPE systems can remove unwanted compounds and streamline methods.

Essential oils have been a staple of the food, fragrance, and health markets for many years. Owing to their unique composition, essential oils can be used for a variety of applications.

This application note showcases the development of two methods using photodiode array detection (PDA) to separate three isomers of tocopherol (vitamin E).

Nitrogen was used as the carrier gas instead of helium Trace amounts of thiophene were easily measured SCD provided excellent sensitivity and selectivity

What you will learn: - New workflow aims to ameliorate the difficulties of water analysis - Incorporates risk assessments/cheminformatics to prioritize suspect chemicals - Strategy increases confidence in the results.

What you will learn: - Automated extraction method achieves higher recoveries - Steps involved in QuEChERs vs. EDGE method

-Automated SIFT–MS increases productivity for thermal desorption tube analysis. -Case studies show that TD–SIFT–MS improves analysis for several applications.

This application note demonstrates a multistep thermal extraction study on tetrahydrocannabinol (THC) vape oils.

Pickering Laboratories developed an easy and sensitive method to analyze aflatoxins B1, B2, G1, G2, and ochratoxin A in hemp and hemp-containing edible products. Mycotoxins are isolated using immunoaffinity clean-up columns and analyzed with fluorescence detection. To increase sensitivity of aflatoxins B1 and G1, an in-line photochemical reactor (UVETM) is installed before the detector. This method utilizes standard HPLC equipment and allows laboratories to easily determine these mycotoxins at low ppb levels.

The oligonucleotide therapeutics field has seen remarkable progress over the last few years and oligonucleotides are increasingly recognized as potential therapeutic agents for a variety of diseases. Here we describe the ability of ultra-high pressure size exclusion chromatography (SEC) to distinguish N and N-1 oligonucleotide species.
