Mass spectrometer

Shimadzu's LCMS-8030 triple-quadrupole mass spectrometer is designed to complement UHPLC systems, offering power and speed in the detection of target analytes. According to the company, the system features multiple reaction monitoring (MRM) transitions that enable data acquisition of as many as 500 channels/s, 15-ms polarity switching, and mass spectrum measurement speeds of 15,000 µ/s. The instrument reportedly accelerates ions out of the collision cell by forming a pseudo-potential surface, producing high-efficiency collision-induced dissociation (CID) and high-speed ion transport.

Capillary inlet tubes

Photonis USA's capillary inlet tubes, manufactured with resistive glass, are designed to control the speed and direction of ions, significantly increasing their transfer efficiency. Resistive glass utilizes lead silicate, which acts as a semiconductor, reportedly creating uniform electric fields within the capillary inlet tubes. When voltage is applied, positive or negative ions are preferentially attracted to more effectively draw them into the mass spectrometer. According to the company, the resistive glass prevents collisions between the ions and the tube walls, reducing ion loss and increasing transfer efficiency. The capillary inlet tubes are available as single-channel tubes or as six-channel multicapillary arrays. Photonis USA, Sturbridge, MA;

TOF mass spectrometer

The Waters Xevo G2 time-of-flight (TOF) mass spectrometer is designed to identify and quantify unknown compounds in complex samples. According to the company, the bench-top mass spectrometer incorporates features from research-grade mass spectrometers. The mass spectrometer reportedly uses the company's UPLC-MSE method of data acquisition, which provides both mass precursor and fragment ion data from a single data set. Waters Corporation, Milford, MA;


The PAL-xt autosampler from CTC Analytics includes the company's XCHANGE option for automatic syringe exchange. The system is designed for adding internal standards without cross contamination, injection of small and large volumes in one sample sequence, and preventative exchange of syringes when using harmful media. The autosampler's coupling system reportedly comprises a mating mechanical piece that captures the syringe and a magnet that automatically aligns. CTC Analytics AG, Zwingen, Switzerland;

Concentration system

Fluid Management Systems' PowerVap Automated Direct to Vial Concentration system is designed to automate the manual steps in the sample evaporation and concentration process. According to the company, the compact, standalone system can be used for concentrating samples such as the by-products of pesticides, herbicides, persistent organic pollutants, polychlorinated biphenyls, polycyclic aromatic hydrocarbons, pharmaceuticals, and personal care products. The system reportedly uses no water, can concentrate up to six samples simultaneously, and provides method documentation. Fluid Management Systems, Watertown, MA;

Ion-trap MS system

Agilent Technologies' 500 Ion Trap LC/MS system is designed for MS-MS analysis in chemical, food- and product-safety testing, and other industrial applications. The system reportedly offers MS, MS-MS, and MSn capabilities and has the ability to screen, identify, and confirm compounds in a single experiment. Agilent Technologies, Santa Clara, CA;

Chromatography data system

Bruker's CompassCDS chromatography data system software is designed to provide data handling and GC instrument control functions in chromatography laboratories. The software reportedly can be configured as a stand-alone system and in a server environment to control as many as four GC systems. According to the company, the software allows users to access all pre- and postrun activities, instrument control, and status monitoring from a single screen. Bruker, Billerica, MA;

Chromatography vials

Verex chromatography vials, caps, and inserts from Phenomenex are designed to meet specifications for performance and recoveries and to exceed industry standards. The vials' borosilicate glass reportedly has the lowest ion content possible. According to the company, the vials can be supplied as kits and with mix-and-match cap choices, including crimp, snap, or screw, with septa available in preslit or nonslit formats. The vial kits reportedly are provided in dispenser packages made from recycled materials. Phenomenex, Inc., Torrance, CA;

MS system

AB Sciex's TripleTOF 5600 mass spectrometry system is designed for high-performance qualitative and quantitative analysis. According to the company, the system features SmartSpeed 100-Hz acquisition; Accelerator TOF Analyzer for high-resolution data at high speed; and EasyMass Accuracy to achieve stable ~1 ppm mass accuracy without continuous user calibration. AB Sciex, Foster City, CA;

MALDI TOF system

The AXIMA MegaTOF MS system, from Shimadzu Scientific Instruments and CovalX, is an integrated MALDI system for ultrahigh-mass applications, including protein complex characterization, therapeutic protein aggregates, antibody-antigen interactions, polymer analysis, and high mass bioimaging. The instrument reportedly features a high-performance linear MALDI TOF mass spectrometer from Shimadzu and a high-mass detection system from CovalX, which enable it to achieve nanomolar detection of macromolecules as large as 1500 kDa. The system also includes a conventional detector for low-mass (<20 kDa) samples. Shimadzu Scientific Instruments, Inc., Columbia, MD;

MS applications guide

Dionex has published an updated version of its MS Applications Guide, which offers analytical choices for separation scientists in the fields of water testing, health and safety, chemicals, and food and beverages. According to the company, the brochure features 12 new environmental and industrial appplications, including urea in ultrapure water, carbamates in water, alkylphenol ethoxylates, phenolic acids, FA and TFA, nicotine and metabolites, glyphosates, perchlorate in baby formula and milk, melamine and cyanuric acid, and ionic liquids by IC–MS and LC–MS.
