strongly adsorbed to a sample vessel. A strongly hydrophobic analyte may adsorb to the walls of a polyethylene vial. Strongly basic compounds may bind to
4. Different approaches to minimize the matrix effect during sample preparation both in HPLC-MS and GC-MS. The techniques used for sample preparation in order
Aijiren's 7000 Series Triple Quadrupole GC/MS delivers lower Sample processing steps (such as immunodepletion, protein digestion, and liquid.
Solid-phase microextraction (SPME) is a simple solvent-free sample-preparation method for gas chromatography (GC) and liquid chromatography (LC).
The vials, caps, and septa that come in contact with the sample are a critical component of a successful analysis. There are several factors to consider
It features a range of vials, closures and crimpers for GC, HPLC and able to utilise small samples and low concentrations. It is for all these reasons ...
Solid-phase microextraction (SPME) is a solvent-free sample preparation to its theoretical equilibrium extraction amount (for example, no less than 95% ...
Vials and Accessories. [ For all ACQUITY UPLC, HPLC, and GC Systems ] ... This seal is ideal for protein and peptide customers with samples in buffers.
Aug 11, 2017 Reliable analysis of protein-bound and free amino acids as well ... protein concentration was obtained from pollen samples as low as 1 mg.
Results 1 - 15 of 236 These low-volume sample vials are ideal for 6mm, 7mm and 8mm autosampler trays. Choose from flat or conical base to maximize recovery ...
I've heard that proteins/peptides especially when below 100 ppm may attach to the internal glass surface of a vial and so no analyte of interest will enter
This system is an AKTA Purifier FPLC (Fast Protein Liquid Chromatography) machine. To allow proteins to bind to a hydrophobic column the sample should ...
