The extraction and segregation of Organic compounds from core samples taken from marine sediments is used to predict climate conditions, reconstruct sea temperatures and identify the type of vegetation from the C3 ( Temperate cli-mate) and C4 ( Tropical Climate) isotopic mass spectroscopy ratio analysis.
With the widespread clinical use of antidepressant drugs comes the need to accurately measure therapeutic lev-els to determine proper dosage, as well as check for toxic levels and patient compliance. More and more laboratories are shifting their therapeutic drug monitor-ing from liquid extraction to solid phase extraction. A large clinical laboratory has automated the process of extracting these drugs from serum using the RapidTrace SPE Workstation.
When analyzing human urine for drugs of abuse, one of the most common tests is for the cocaine metabolite Benzoylecgonine (BZE). A contract laboratory has automated this labor intensive procedure using the RapidTrace.
In order to keep your RapidTrace® workstation clean, in good working order and free from contamination it is of course essential to routinely clean and purge the fluid path. Whichever matrix and reagents are running through the system, traces of these liquids will be left after use; proteins from plasma, precipitates from buffers or even particulates from oral fluid. Over time if the following cleaning schedule is not observed these contaminants could cause blockages leading to malfunctions and/or cross contamination.
Ethyl glucuronide (EtG, Figure 1.) is an ethanol metabolite formed by the glucuronidation of the parent molecule. The presence of EtG in urine and plasma is a useful and sensitive biomarker of alcohol intake in forensic toxicology. EtG can be detected at very low levels and is useful in distinguishing between ingested ethanol and that which is adsorbed through the skin from ethanol. This application note has been optimized on the RapidTrace+; an updated version of the current RapidTrace software which allows the system to process smaller bed heights than were previously possible. The application note shows analyte recoveries all above 97% with RSDs >10%. EVOLUTE, Resin, EtG, Alcohol, Alcohol Biomarker, metabolite, anion exchange, Strata X, Oasis, Waters,
Melamine is traditionally used in making plastics, however, it’s low cost and high nitrogen content has led to exploitation in various sections of the food industry, most notably involving dairy products. Sustained melamine exposure can result in kidney stones and renal failure, with the young being most susceptible. This application note has been optimized on the RapidTrace+; an updated version of the current RapidTrace software which allows the system to process smaller bed heights than were previously possible. The application note shows recoveries of 88-90% with RSDs <10%. Melamine, food scare, china, EVOLUTE, cation exchange, RapidTrace, Automation, SPE, sample prep,
The use of schedule I drugs for patient pain management therapy warrants constant monitoring of therapeutic levels in the patient. Screening patient urine samples for the free drugs is complicated by the metabolism process which converts the free drug to the -glucuronide form. Patient urine samples can be enzymatically hydrolyzed to cleave glucuronide moiety and produce the free form of drug. The target analytes can them be extracted from the urine matrix using EVOLUTE CX solid phase extraction cartridges.

Cyclosporine (Figure 1) is an immunosuppressant drug most significantly used in post-operative organ transplants to reduce the chance of rejection of donor organs by decreasing the activity of the patient’s immune system. Subsequent to an organ transplant, patients are tested at regular intervals for the presence of very low levels of the compound. Cyclosporine is a cyclic non-ribosomal peptide of 11 amino acids and contains a single D-amino acid. Cyclosporine, Cyclosporine, Immunosuppressant,

User report: RapidTrace. The Laboratory of Racing Chemistry (LRC) analyzes samples from racehorses for doping drug. In order to screen approximately 1000 samples per week, LRC use an array of Biotage RapidTrace automated SPE systems. In an interview, Mr. Kenji Kinoshita and Mr. Kensaku Shirai talked about their experiences with the RapidTrace system in processing the heavy workload.
