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
2-Mercaptoethanol (2-ME) is a reducing agent used in synthetic and biological applications. This reducing agent is offered in multiple sizes to maximize its efficiency and shelf life. CovaChem's 2-Mercaptoethanol (11301-10 x 1 g) is designed for use in biological assays. These 1 gram hermetically sealed ampules provide maximum protection of the active thiol group and inconsistent activity from use to use or bottle to bottle.
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.
Biotin is a compound used to biotinylate proteins with the addition of a zero length cross linking reagent. D-Biotin has several biology research applications, where the avidin biotin interaction is utilized.
LCMS Grade Propionic acid (Ultra High Purity) from CovaChem is well suited for HPLC and LCMS applications. Propionic acid can be used as a mobile phase for HPLC or LCMS, or can be used post-column in LCMS applications to increase ionization efficiencies when ion pairing agents are used for separation.
