Evaporator aids forensic science

Genevac’s EZ-2 Series centrifugal evaporator is being used by a growing number of forensic science labs as a sample preparation tool for applications including drug and alcohol testing as well as toxicological screening.

Forensic investigations often use the sensitivity and identifying power of mass spectrometry (MS), typically with solid phase extraction and evaporation as part of the sample preparation process. Blood and urine analysis are widely used for forensic investigations into drug-related deaths, drug-facilitated crimes and in the clinical assessment of alcohol and drug consumption. Hair analysis can also provide evidence of drug or alcohol abuse over time, as part of programme compliance for those participating in drug or alcohol dependency treatment or for workplace or health insurance screenings. The EZ-2 streamlines the sample preparation process whilst maintaining sample integrity and improving sensitivity.

Using Genevac’s Dri-Pure sample protection system, the EZ-2 can dry forensic samples without cross-contamination and sample loss due to solvent bumping, which is commonly experienced with some other evaporator systems. 

“To enable all users to achieve higher recoveries for volatile analytes and repeatable results each time, the EZ-2 has been made easier to use than some conventional nitrogen blowdown systems,” said Genevac Product Manager Dr. Induka Abeysena, who says that addition to accommodating many samples, the centrifugal evaporator can operate entirely unattended. 

“Beneficially, the EZ-2 temperature control and auto-stop systems protect and ensure sample integrity, to provide extra peace of mind with thermally sensitive samples,” said Abeysena.
