A procedure for cleanup of green tea extracts provides low background and allowed for the analysis of more pesticides at lower levels than QuEChERS. Uses less solvents and no toluene.
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.
Compared to conventional PSA/C18/GCB cleanup, cannabis extracts cleaned with the Supel QuE Verde mixture showed lower GC/MS background, and better recoveries for many pesticides.
The odor and pungency of ginger is due to the presence of terpenes, gingerols and shogaols. These compounds contribute to the highly complex matrix of ginger, which subsequently presents a challenge in low level analyses of contaminants. A novel 2-layer

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.
Cell lines for vaccine production and cultivation of SARS CoV-2 and other viruses. Primary, human diploid, and continuous culture cell lines for the propagation of viruses and virus-based vaccines.
Pistachios contain approximately 45% fat, which can result in a significant amount of coextracted matrix in the acetonitrile extract generated using the QuEChERS procedure. A zirconia based adsorbent significantly reduces coextracted matrix prior to LC-MS or GC-MS.
Check the solubility of 128 common inorganic compounds (salts and acids) in water at different temperatures from 0 degrees Celsius to 100 C. Compound formulas are also given in this table of solubility in relation to temperature.
Use the calculator to determine the boiling point or pressure of solvents based on the Antoine Equation and see solvent attributes. View a list of products based on the solvent CAS number.
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
This page clarifies sample preparation, buffer exchange and desalting, removal of lipoproteins, phenol red, and low molecular weight contaminants in Ion exchange chromatography.
Explore the role of some selected GPCR markers in cancer research development and treatment, including neurohormonal GPCRs, rhodopsin-like GPCRs, and more.
Overcome challenges in synthesis and disulfide bond formation with protocols for Fmoc solid-phase peptide synthesis of peptides with cysteine and methionine.
Using the 40 µm aperture sensor, the Scepter cell counter can accurately and precisely count a broad range of cell types, including small cells such as PBMC and red blood cells.
Silica is a very popular inorganic nanomaterial used in a wide range of applications including fillers for rubber, catalyst supports, separation media, carriers in food and agriculture, and abrasive/anticaking agents in cosmetics. It is also widely believed to be an
Advanced technologies for energy conversion and storage are widely sought after for their potential to improve consumer and electronic device performance as well as for the prospect of reducing the societal and environmental impact of energy generation.
Biomedical implants are essentially foreign substances within the human body that must survive many years’ exposure to demanding mechanical and physiological conditions. Despite these challenges, metal implants have been widely used to substitute for or rebuild hard tissues such as
Poly(2-oxazoline)s (POx) can be viewed as conformational isomers of polypeptides. They are synthesized via living cationic ringopening polymerization (LCROP) of 2-oxazolines and were almost simultaneously discovered in 1966 by the groups of Litt, Tomalia, Fukui and Seeliger.
Titanium dioxide (TiO2) is an important n-type semiconducting material that shows interesting characteristics such as photoswitchable surface wettability, high photocatalytic activity, bistable electrical resistance states and high electron drift mobility.
In this paper, we discuss recent advances in the preparation of various TiO2 porous structures via hard and soft-templating routes. Specifically, we focus on recent developments in TiO2 mesoporous thin films in a combined sol-gel and evaporation-induced self-assembly (EISA) process.
Research evaluating immune checkpoints may help identify those likely to benefit from PD-1/PD-L1 immunotherapy and reveal new immunotherapy targets for future investigation. See how the MILLIPLEX® Human Immuno-Oncology Checkpoint Protein Panel 2 was used to multiplex immune checkpoint molecules for
Graphene is a unique two-dimensional (2D) structure of monolayer
carbon atoms packed into a dense honeycomb crystal that has attracted
great interest due to its diverse and fascinating properties.
