TurboVap® 96 Dual: Simplifying high-throughput sample preparation
Part I: Principles of evaporation Evaporation is a process used to concentrate samples by vaporizing and removing liquid solvents, leaving behind the dissolved solid components. Evaporation is essenti...
The benefits of automating sample preparation
The main purpose of sample preparation is to extract the target analyte(s) from the sample matrix, allowing them to be measured by the chosen analytical technique, such as LC-MS/MS or GC-MS. This can ...
Extraction of catecholamine acid metabolites from plasma
Catecholamine metabolites vanillylmandelic acid (VMA), homovanillic acid (HVA) and 5-hydroxyindoleacetic acid (5-HIAA) are biomarkers for neuroblastoma and catecholamine secreting tumours. We present ...
A comparison of current methodologies for extraction of DoA from urine
Urine is a very useful matrix in forensic laboratories, because it is easy to collect and can help determine if a drug has been used recently. There are many viable sample preparation options for urin...
Practical considerations using Quantisal oral fluid collection devices
