Methods Employed Prior to LC-MS

Benzodiazepines  GC-MS

Opiates  GC-MS

Other drugs of abuse group 1  ELISA

(4)

Why switch to LC-MS method?

Benefits of replacing GC-MS

• Faster  less need for chromatographic separation

• Less sample prep  no derivatization

• No thermal instability  benzodiazepines analysis

• No volatility limitations

Benefits of replacing immunoassay

Lower consumables cost

More specific

(5)

Goal

Develop fast, easy to use, generic LC-MS method to analyze

multiple classes of drugs of abuse in urine

Method has to meet industry standards for

• Precision

• Accuracy

• Limit of quantitation

• Robustness

• With simplest sample prep procedure

Opiates

Benzodiazepines
