Analysis of Pesticides in Turmeric Powder by LC/MS/MS and GC/MS/MS after Cleanup with Dual-Layer SPE Cartridge
Pesticide residue testing of turmeric and other (dried) spices is challenging due to their complex compositions and high matrix. An efficient SPE clean-up can be achieved by a new Dual-layer cartridge.
Evolving CBD Regulations – Impact on Cosmetics and Skincare
While governmental regulations on cannabidiol and other cannabinoids are not yet harmonized around the globe, many countries are legalizing their use and that is a sign that the demand for CBD in cosmetics and skincare will continue to grow.
Dextran
Dextran is a polymer of anhydroglucose. It is composed of approximately 95% alpha-D-(1-6) linkages. The remaining a(1-3) linkages account for the branching of dextran. Conflicting data on the branch lengths implies that the average branch length is less than three
Simplified LC-MS/MS Method for Glyphosate, AMPA, and Glufosinate in Oat-Based Cereals
A simplified LC-MS/MS method to determine glyphosate and related compounds using a Supel™ Carbon LC U/HPLC column for stability under higher pH conditions and sufficient retention for the polar analytes in the presence of methanol as an extraction solvent.
Overcoming Aggregation in Solid-phase Peptide Synthesis
The ease of assembly of a given peptide sequence is hard to predict, which makes peptide synthesis challenging. Review methods and reagents for avoiding aggregation in solid-phase peptide synthesis.
Determination of PAHs in Paprika Powder Using a Novel SPE Cartridge
Paprika is a spice made from dried sweet peppers, and is used for flavor and color in many types of cuisine. Contamination with polynuclear aromatic hydrocarbons (PAHs) can occur when pepper plants are exposed to these pollutants in the environment
