Beschreibung

Anwendung

• Suitability evaluation of new endogenous biomarkers for the identification of nitrite-based urine adulteration in mass spectrometry methods.: This paper assesses novel biomarkers for spotting urine tampering using potassium nitrite, critical for maintaining integrity in analytical testing scenarios (Steuer et al., 2019).
• 2-Nitro-6-monoacetylmorphine: potential marker for monitoring the presence of 6-monoacetylmorphine in urine adulterated with potassium nitrite.: Introduces a potential marker for detecting adulteration in urine tests, essential for chemists focused on drug testing accuracy (Luong et al., 2012).
