General Extraction
- Extract over 11 drugs using the same sorbent
- Consolidate methods; 3 methods is all you’ll need to extract 6 different drug classes
- Time and solvent savings; no conditioning required
- Consistent, sensitive, and high recoveries of SAMHSA regulated drugs
Retention Mechanism
Strata-X Drug B Protocol
Strata-X Drug B Plus Protocol
Starting Method
General Urine Pre-treatment Recommendation
- Combine urine sample with appropriate buffer.
- Add β-Glucuronidase enzyme according to manufacturer’s recommendation (If using Strata-X-Drug B Plus, these steps can be performed in-well).
- Incubate for specified amount of time (If using Strata-X-Drug B Plus, pulse vacuum to load solution onto sorbent).
- Follow appropriate SPE protocol based on analytes of interest.

* Opiates, 6-MAM, PCP, Amphetamines, Propoxyphene, Healthcare Opiates, and Methadone can be extracted simultaneously or separately using the same SPE methodology. Methods are written for 30 mg/well Strata-X-Drug B 96-well plate; however they can be scaled to accommodate smaller or larger sample sizes and sorbent masses.
