MethElute Reagent (TMPAH) Provides accurate sensitive on-column methylation
• 0.2M trimethylanilinium hydroxide (TMPAH) in methanol solution
• For quantitative methylation and detection of barbiturates, sedatives, xanthine bases, phenolic alkaloids and phenytoin by gas chromatography
• Single quantitative peak for each substance
• Comparable to or better than UV/TLC method (when phenobarbitol and phenytoin are present, GC is superior to UV/TLC)
• Coefficient of variation is 5% or less
• Detects barbiturates to 0.2mg/dL
