AB Sciex this week introduced its new TripleQuad 4500 triple quadrupole mass spectrometer, a mid-range instrument for routine screening and quantitation of analytes including peptides and proteins.
The instrument comes with the option of AB Sciex's QTRAP technology and offers 10 times the sensitivity of comparable mid-range triple-quads, the company said.
AB Sciex also released this week its new Eksigent ekspert microLC 200 System, a micro-UHPLC system designed for high-throughput protein and peptide quantitation.
The system offers improvements in separation speed and sensitivity while reducing sample consumption, the company said.
Waters this week launched its new Acquity UPC(2) chromatography system, an UltraPerformance Convergence Chromatography system that uses compressed carbon dioxide as its primary mobile phase.
The system offers a replacement for normal phase chromatography and enables the separation of compounds that are difficult to analyze via LC and GC, the company said.
Waters also introduced a new line of chemical reagents and standards for LC and LC-MS.
The new reagents range from "pre-formulated, small molecule, single-component standards to multi-component test mixes to protein digest and glycan standards" and will help researchers reduce analytical variability, the company said.
Thermo Fisher Scientific this week launched its new NanoDrop Lite spectrophotometer for basic measurements of nucleic acid and protein concentrations.
The device is a compact instrument intended to complement the company's full-featured NanoDrop machines, it said.
EMD Millipore this week released its new Direct Detect protein quantitation system.
The system uses a combination of membrane technology and infrared (IR)-based spectrometry, which allows for protein quantitation with little sample prep and small sample amounts, the company said.
SiliCycle this week introduced its new SiliaPrepX line of polymeric SPE cartridges and well plates for solid phase extraction.
The line includes hydrophilic-lipophilic balance, divinylbenzene, strong cation and anion exchangers, as well as weak cation and anion exchangers and allows treatment of common matrices including human and animal biological fluids.
