Merck, 1055770001, TLC plastic sheets, Cellulose

General description
25 Plastic sheets 20 x 20 cm
Our Cellulose plates are used to analyze polar substances. An organic sorbent, cellulose is perfect for separating hydrophilic substances by partition chromatography. Typical applications include the analysis of amino acids, carbohydrates, and phosphates as well as nucleic acid and nucleic acid derivatives. We offer cellulose plates in two grades: TLC for conventional and HPTLC for demanding, high-performance separations.
Application

A colorimetric method for the enzymatic analysis of gases: the determination of ethanol and formaldehyde vapors using solid alcohol oxidase.: This study presents a novel colorimetric method utilizing solid alcohol oxidase for the determination of ethanol and formaldehyde vapors. The technique, employing cellulose TLC plastic sheets, provides an efficient and accurate means of gas analysis in various environments (Barzana et al., 1989).
