Pharmaceutical companies and those who supply them with intermediates, constantly strive to produce API’s and
intermediates of the highest purity. At the same time, many established production facilities face strong competitive
pressures to produce high quality product at lower costs. Drug substance impurities are wide-ranging as described in the
International Conference on Harmonization (ICH) “Impurities in new Drug Substances”1. Of particular concern in recent
years are the ‘genotoxic compounds.

This methodology has been designed to give an effective and efficient supported liquid extraction protocol for the clean-up and concentration of salivary cortisol levels. Cortisol is a steroid hormone that when measured from saliva can be used as an indication of stress. Analyte recoveries achieved using this method ranged from 96-99% with RSDs below 3% (n=7) for all analytes.

This application note describes the extraction of 11-nor-9-carboxy-THC from a urine matrix, prior to GC/MS analysis.
Carboxy-THC is the primary metabolite of THC, a key indicator of illicit marijuana usage. In urine, ~80% of the carboxy-THC metabolite is present in the form of its glucuronide metabolite. Therefore, to effectively quantify the THC-COOH, urine is hydrolyzed before extraction. This application note describes optimized extraction of urine samples prepared by either enzymatic or base hydrolysis.

This application note describes the extraction of THC and metabolites from urine using ISOLUTE SLE+ columns or plates. The most prevalent marker in biological samples taken from cannabis abusers is 11-nor-9-carboxy-Δ9-THC. Here we demonstrate a supported liquid extraction procedure for 11-nor-9-carboxy-Δ9-THC.

The use of schedule I drugs for patient pain management therapy warrants constant monitoring of therapeutic levels in patient urine samples. Screening patient urine samples is further complicated by the metabolic process which converts the free drug to the - glucuronide form. The target drugs in patient urine samples can be enzymatically hydrolysed and extracted using Supported Liquid Extraction (ISOLUTE SLE+) which offers an efficient alternative to traditional liquid-liquid extraction (LLE) and solid phase extraction (SPE) techniques typically used for this type of clinical sample preparation.

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 and extracted to detect the drugs using Supported Liquid Extraction (ISOLUTE SLE+) which offers an efficient alternative to traditional liquid-liquid extraction (LLE) for bioanalytical sample preparation. LOQs for recovered drugs ranged from 10 ng/mL to 0.5 ng/mL with recoveries above 80% and RSDs <10%

This application note describes a SPE-UHPLC-MS/MS procedure for the analysis of 8-oxodG, a biomarker of oxidative stress, from various human biofluids using ISOLUTE ENV+ solid phase extraction columns. Oxidative stress is the imbalance between the production of reactive oxygen species (ROS) and the body’s ability to eliminate them, in favour of the former. ROS have been linked with development of numerous diseases including Parkinson’s and Alzheimer’s and have also been associated with fertility problems. 8-Oxo-7,8-dihydro-2'-deoxyguanosine (8-oxodG) is one of the mutagenic nucleobase modifications produced in DNA and the 2’deoxyribonucleotide pool, by the reaction of ROS. Measurement of 8-oxodG in biological fluids can provide a useful indicator of oxidative stress.
