18 Environmental Laboratory Application Note for Analysis of Microcystin Toxin in Drinking Water
Bruker (USA) has released an Application Note detailing the development for analysis of microcystins in drinking water, by direct injection on the recently introduced EVOQ Elite liquid chromatography mass spectrometer triple quadrupole(LC-MS/MS). Microcystins (MCs) are cyclic heptapeptides produced by cyanobacteria in lakes and reservoirs that experience seasonal algal bloom. MCs are toxic to animals and humans, with widespread adoption of the World Health Organisation’s (WHO) guidelines of 1µg/L in drinking water. Using the EVOQ Elite LC-MS, Bruker has developed the method for the detection and quantification of three common MCs (MC-LR, -YR, -RR) in drinking water to ensure its safety. The Application Note is available to download at

The Application Note explores the high sensitivity of the EVOQ Elite LC-MS/MS, in detecting parts per billion (ppb) concentrations of MCs. Water containing three common cyanobacterial toxins was directly injected into the EVOQ. The MCs were examined over three orders of dynamic range, from 50 ppb to 0.05 ppb. The EVOQ proved sensitive to detect 0.00 ppb of MCs with good repeatability of <10% relative standard deviation (RSD), far exceeding the guideline set by the WHO of 1µ/L, demonstrating that the EVOQ Elite can easily be utilised to ensure safe levels of MCs in drinking water.
Meredith Conoley, Bruker CAM Marketing Director, explained that “The EVOQ Elite is designed to deliver game-changing performance for laboratories involved in high throughput quantitation. Innovations in hardware, including the revolutionary Active Exhaust and Orifice Interface, have contributed to an LC-MS/MS of
exceptional sensitivity, while the EVOQ’s IQ Dual Ion Funnel, VIP-HESI and the new PACER software make it user-friendly and cost-effective.” Conoley went on to say that “with its sustained high performance, the EVOQ Elite offers advantages to any lab conducting routine analysis of water quality, as well as environmental monitoring and food testing.”

Reader Reply Card No. Chiral Screening Services Now Offered in China
Phenomenex (USA), a global specialist in the research and manufacture of advanced technologies for the separation sciences, have announced the extension of its Chiral Screening Service to pharmaceutical and natural products customers in China. The service is offered in collaboration with the Chinese Academy of Sciences (CAS), a leading academic and R&D centre under which the Shanghai Institute of Organic Chemistry (SIOC) has developed a strong chiral team that works closely with Phenomenex. The free Chiral Screening Service provides target screening using a library of HPLC columns including the Phenomenex Lux polysaccharide-based offerings, which demonstrate a success rate approaching 90 percent. After resolving the chiral compound, Phenomenex delivers a method development and optimisation plan to the customer within 10 business days – the same rapid turnaround the service promises in the U.S. and Europe.
“Our customer base in China has been growing rapidly and the expansion of our services will help us better serve them,” explains Michael Klein, brand manager for Phenomenex. “By teaming up with the CAS-SIOC, we are able to quickly roll out our rapid-response service.”
Enantiomers of chiral compounds may have different pharmacological effects in biological systems and they must be identified and evaluated separately. “Resolving chiral compounds is relatively difficult, and column selection can be complicated,” continues Klein. “Our Chiral Screening Service eliminates time-consuming guesswork and also
gives customers a chance to ‘test-drive’ our Lux columns.”
The Phenomenex team of chiral experts will customise a plan for each screening project, taking into account specific requirements and overall separation goals. Once a project is completed, the customer will receive a report that details the optimal method including information on the chiral stationary phase (CSP) selected for the separation, running conditions and associated chromatograms.
