Closing the door on drug-facilitated crimes: detecting “date rape” drugs in drinks

Date: Jan 1, 2016

Author: Ryan De Vooght-Johnson

Benzodiazepines are effectively used to treat anxiety and insomnia, but are frequently hijacked for illegal purposes. A method for their rapid detection in alcoholic beverages is reported by a new paper, which has implications for trials for drug-related crime.

Journal Highlight: A new approach to live reaction monitoring using active flow technology in ultra-high-speed HPLC with mass spectral detection

Date: Dec 21, 2015

Author: separationsNOW

A new type of chromatography column referred to as a parallel segmented flow column enables ultra-high-speed high-performance liquid chromatography-MS to be undertaken, with LC separations within 12 s.

Marijuana mimics detected in urine

Date: Dec 14, 2015

Author: Ryan De Vooght-Johnson

There are serious safety concerns about synthetic psychoactive substances, often used as ‘legal highs’. A new study reports the use of LC-MS to identify metabolites of synthetic cannabis in urine, which will enable accurate drug testing.

Corticosteroid-containing creams: identifying risk to children

Date: Dec 1, 2015

Author: Ryan De Vooght-Johnson

Corticosteroid-like compounds found in skin creams can have dangerous side effects, especially in children. A new chromatography-based method to detect and identify them may improve regulation and reduce risk.

Journal Highlight: Simultaneous determination of three banned psychiatric drugs in pig feed and tissue using solid-phase reactor on-line oxidizing and HPLC-fluorescence detection

Date: Nov 23, 2015

Author: separationsNOW

A novel HPLC-fluorescence detection method based on post-column on-line oxidization with lead dioxide has been developed for the simultaneous determination of three banned psychotropic drugs, promethazine, chlorpromazine and thioridazine, in pig feed and tissue.

Deadly puffer fish toxin measured in seafood

Date: Nov 1, 2015

Author: Ryan De Vooght-Johnson

Tetrodotoxin is a poisonous toxin found in seafood, most notably puffer fish. In a newly published study, researchers describe a method to quantify it in cooked seafood, something that has previously proven difficult owing to the matrix effect.

Journal Highlight: Quantitation of synthetic cannabinoids in plant materials using high performance liquid chromatography with UV detection (validated method)

Date: Oct 19, 2015

Author: separationsNOW

A validated, broadly applicable HPLC-UV method for the determination of synthetic cannabinoids in plant materials is presented and validated for several structural classes such as dibenzopyrans, cyclohexylphenols and naphthoyl-, benzoyl-, phenylacetyl- and tetramethylcyclopropyl-indoles.

Waste not, want not: sweet fuel from sugarcane debris

Date: Oct 12, 2015

Author: Ryan De Vooght-Johnson

Lignocellulose, the woody material in plants, is a source of renewable fuel. In this study, HPLC was used to separate, identify and quantify compounds in sugarcane that prevent it being converted to ethanol, a powerful biofuel.

Mass spectrometry-based proteomics identifies biomarkers for septic shock

Date: Oct 1, 2015

Author: Ryan De Vooght-Johnson

Identifying systemic inflammatory response to infection early is vital. If the condition progresses to severe sepsis or septic shock, it can soon be fatal. Biomarkers for sepsis are therefore a key goal for research in the area, as they would enable more rapid diagnosis and treatment.

Journal Highlight: Simple correction improving long-term reproducibility of HPLC–MS

Date: Sep 21, 2015

Author: separationsNOW

A simple correction algorithm based on polynomial fitting was proposed to correct the variation in chromatographic peak areas in long experiments that introduces bias to the results.
