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.

3-Maleimidopropionic acid N-hydroxysuccinimide ester (BMPS) is a heterobifunctional crosslinker with a spacer length of 6.9 Å. BMPS contains an amine reactive, NHS ester, and a maleimide group which is reactive towards sulfhydryl functional groups.
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.
Citraconic Anhydride (Methylmaleic anhydride) is used to block primary amine (-NH2) groups at pH 7 to 9. Citraconic anhydride reacts with primary amines to create a reversible amide linkage, which can be reversed under acidic conditions or in the presence of hydroxylamine.
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.
