HPLC columns, SeQuant® ZIC®-cHILIC

HPLC columns, SeQuant® ZIC®-cHILIC

Supplier: Merck

ZIC®-cHILIC is based on the same technology platform as ZIC®-HILIC, but has a different functional group and an improved manufacturing procedure. The different charge orientation of the zwitterionic functional group leads to a different – and complementary – selectivity for polar hydrophilic compounds. This selectivity is especially beneficial for hydrophilic compounds that are negatively charged, positively charged, zwitterionic or neutral, for example, organic acids, amino acids, metabolites, aminoglycosides and nucleotides.

Formaldehyde ≥37% vodný roztok stabilizovaný, GR ACS, Reag. Ph. Eur. analytical reagent, Sigma-Aldrich®

Supplier: Merck

—Formaldehyde (HCOH) is one of the most familiar and effective fixatives. The fixation of the histological specimen material of human or animal origin is commonly performed in a 4% or 10% Formaldehyde solution. Chemically, the 4 % Formaldehyde solution equals a 10 % Formalin solution. The Formaldehyde solution min. 37% is a stock solution that is used for histology and can be diluted with e.g. PBS to 4% ready-to-use fixation solution.
