Applied Biosystems announced this week the launch of two mass spectrometers: the 3200 Q TRAP and the API 3200 LC/MS/MS. By incorporating the ABI/MDS SCIEX Turbo V source and the API 4000 LC/MS/MS interfaces and ionization sources into a smaller platforms, the two new mass spec systems provide increased sensitivity, greater flexibility and improved ease-of-use when compared to similarly-priced instruments, the company said.

According to ABI, the 3200 QTRAP provides a greater-than-two-fold increase in sensitivity in linear ion trap mode at all flow rates, and up to a five-fold signal-to-noise increase in traditional triple quadrupole mode, over its predecessor, the ABI QTRAP LC/MS/MS system.

The API 3200 LC/MS/MS System offers improved sensitivity, speed, and simplified sample preparation for pharmaceutical, environmental and forensic markets, ABI said.


GWC Technologies launched this week its SpotReady series of chips for label-free array analysis of proteins and other biomolecules. The products are designed to work with the company's SPRimager and SPRimagerII systems to make proteomic analysis faster, easier and more reliable.

SpotReady chips are made out of special glass that is coated with a hydrophobic background. Each chip has 16 or 25 grid spots that can be manually loaded with protein or other probes.
