CovaChem's LCMS Grade Acetic Acid is ideally suited as a chromatography additive for use in both HPLC and LCMS applications. Acetic acid is typically beneficial as a separations enhancer, and has a weak ion pairing effect in the mass spectrometer, making dissociation of from the analytes relatively easy, often resulting in increased ionization efficiencies. CovaChem's LCMS Grade Acetic Acid comes in two convenient package sizes (10 x 1 mL Ampules and 25 mL bottles). The 1 mL Ampules of LCMS Grade Acetic Acid are useful for quickly preparing 1 Liter bottles of 0.1% Acetic Acid solutions in either water or other organic solvents.
Package Sizes: 10 x 1 mL and 25 mL
Product Numbers: 11201-10x1 or 11201-25
N,O-bis-(trimethylsilyl) acetamide (BSA) is a silylation reagent used to form stable TMS derivatives that are volatile. BSA is used to derivatize carboxylic acids, phenols, steroids, amines, alcohols, and alkaloids.
N,O-bis(trimethylsilyl)trifluoroacetamide (BSTFA) is a versatile silylation reagent used to form stable TMS derivatives that are volatile. BSTFA is used to derivatize carboxylic acids, phenols, steroids, amines, alcohols, and alkaloids.
3,3'-Dithiobis(sulfosuccinimidyl propionate), commonly known as DTSSP, is a reducible amine reactive protein crosslinking reagent. DTSSP is water soluble, and does not permeate the cell membrane.
N-Ethyl-N'(3-dimethylaminopropyl)carbodiimide hydrochloride (EDC-HCl) is a zero length protein crosslinker. Also known as EDAC-HCl, this reagent is often used with either Sulfo-NHS (CovaChem 13505) or NHS (CovaChem 13504). EDC functions by activating the carboxyl region of the protein or other molecule, and coupling it to an amine or other nucleophilic functional group.
N-(∑-Maleimidocaproyloxy) succinimide ester(EMCS) is a heterobifunctional crosslinker with a spacer length of 9.4 Å. EMCS contains an amine reactive, NHS ester, and a maleimide group which is reactive towards sulfhydryl functional groups.
4-Maleimidobutyric acid N-hydroxysuccinimide ester (GMBS) is a heterobifunctional crosslinker with a spacer length of 7.4 Å. BMPS contains an amine reactive, NHS ester, and a maleimide group which is reactive towards sulfhydryl functional groups.
