Product Information
Phase Detail
Strata-X-Drug B and Strata-X-Drug B SPE Products
Strata-X-Drug-B solid phase extraction (SPE) sorbent is a polymeric specialty phase that can be used to cleanup basic drugs of abuse

Strata-X-Drug B and Strata-X-Drug B SPE Products

Quick and In-Well Hydrolysis Solid Phase Extraction (SPE)

Proprietary sorbent that is designed and quality controlled for basic drugs of abuse analysis. This sorbent does not require a conditioning/equilibration step to save time and help improve throughput. With Strata-X-Drug B Plus, the hydrolysis step is performed in the well, providing even more time savings and reducing transfer steps.

  • QC Tested for Drug of Abuse
  • No Conditioning or Equilibration Steps Required

Brand
Strata-X
Recommended Use
Extraction of basic drugs from biological samples

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

  1. Combine urine sample with appropriate buffer.
  2. Add β-Glucuronidase enzyme according to manufacturer’s recommendation (If using Strata-X-Drug B Plus, these steps can be performed in-well).
  3. Incubate for specified amount of time (If using Strata-X-Drug B Plus,     pulse vacuum to load solution onto sorbent).
  4. 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.
