Forensics

DNA analysis is becoming more and more important in crime investigations. The growth of forensic databases and the introduction of increasingly sophisticated analytical methods has resulted in higher numbers of samples that need to be processed in forensic laboratories.

With the improved sensitivity and reliability of molecular technologies, genetic analysis is going beyond identification of individuals. Information on physical or personal features based on genetic characteristics is also investigated. The increased number of samples created by these developments has lead to the adoption of robotic platforms and data analysis tools in many forensic laboratories.

Extensive monitoring features make Hamilton’s liquid handling workstations are particularly well suited to the high level of process safety and reliability required in forensic laboratories.

Drugs of Abuse Testing

Liquid-liquid and Solid Phase Extraction (SPE) techniques are used for isolation and purification of drugs of abuse and their metabolites. Samples are then characterized using technologies such as GC/MS, HPLC or immuno-assay analysis. When large quantities of samples need to be processed in a reproducible way, liquid handling workstations are often the first choice. HAMILTON's unique pressure Liquid Level Detection (pLLD) and Monitored Air Displacement (MAD) technology increase process safety and reliability during sample preparation.
