Applied Biosystems and MDS Analytical Technologies this week launched two new mass spectrometry systems, the AB Sciex Triple Quad 5500 and the AB Sciex QTrap 5500.
 
The Triple Quad 5500 combines “industry-leading” sensitivity with a new pulse-counting detector called AcQuRate that detects ions to increase quantitative accuracy and precision, enabling a five-fold increase in sensitivity compared to other triple-quad instruments, the company said in a statement.
 
The QTrap 5500 combines a new ion trap technology, Linear Accelerator Trap, with triple quad capabilities, allowing scientists to both identify and confirm results in a single analysis. In qualitative mode, the system can provide up to 100 times greater sensitivity. It also provides ultra-fast scanning and high capacity provided by new electronics and the Linear Accelerator Trap.
 
During a webcast announcing the launches, officials from both companies said that a new workflow was built from the ground up in designing the new systems incorporating new state-of-the-art electronics, new ion optics architecture, and a 44 percent smaller footprint than previous systems.
 
Andy Boorn, president of MDS Analytical Technologies, whose parent firm MDS has a joint venture partnership with ABI on mass specs, said that the launches are meant as additions to its instrument portfolio, not as replacements to existing instruments.
 
The instruments are in manufacturing and are ready to ship now, said Laura Lauman, president of ABI’s proteomics and small-molecules division.
 

 
GE Healthcare this week introduced the AxiChrom columns.
 
The columns are designed to support the lean-enabling approach to column operation and maintenance and have a novel design with a pivot or swing-out column tube for easy access to maintenance. They are designed to enable predictable scale-up ensuring reproducibility over a range of column diameters and lengths, easing scale-up and ensuring consistency between manufacturing locations.
 

The columns are available with diameters from 50 to 1,000 mm.
