MethElute™ reagent (TMPAH), 1 ml vial, 10 pc/PAK

Use Thermo Scientific™ MethElute™ Reagent (TMPAH) for accurate and sensitive column methylation and detection by GC analysis. It is ideal for quantitative methylation and detection of barbiturates, sedatives, xanthine bases, phenolic alkaloids and phenytoin because it produces a single quantitative peak for each substance. When the reagent is heated with drug-containing extracts, serum or urine, drugs containing reactive amino, hydroxyl or carboxyl functions are methylated at the reactive sites.

Performance data
Accuracy is comparable to or better than UV/TLC (GC is superior to UV/TLC in the presence of phenobarbitol and phenytoin)
High precision, with a maximum coefficient of variation of 5%
High sensitivity; Barbiturates can be detected up to 0.2 mg/dl
