Cartridge-based trap system

The cartridge-based EXP nano trap system from Optimize Technologies is designed to remove detergents or salts that can affect the ionization process in an ultrahigh-pressure liquid chromatography–mass spectrometry analysis. According to the company, the hardware is rated to greater than 20,000 psi (1400 bar). Users reportedly can exchange trap columns by hand without breaking any fluid connections. Optimize Technologies, Oregon City, OR;

ICP-MS system

The Agilent 8800 triple-quadrupole ICP-MS system is designed to provide improved performance compared with single-quadrupole ICP-MS and to provide MS-MS operation for interference removal in reaction mode. According to the company, the system can be used to analyze elements in life-science, soil, rock, and plant materials. The system reportedly also can be set up to operate like a single-quadrupole ICP-MS system. Agilent Technologies, Santa Clara, CA;

Portable GC–MS system

The Tridion-9 portable GC–toroidal mass spectrometry system from Torion is designed for field GC–MS applications. The system reportedly combines an electronic pressure controlled gas chromatograph with an amplitude scanning toroidal ion trap mass spectrometer. According to the company, the system can be used with SPME syringes for sample introduction. Torion Technologies Inc., American Fork, UT;

Resistive glass tubes

Resistive glass tubes from Photonis are designed with nonlinear gradient electrical resistance changes. According to the company, the process can be used to create a solid-piece reflectron lens for use in reflectron-type time-of-flight mass spectrometers. Photonis, Sturbridge, MA;

Wine standards

Certified reference materials for trace metals analysis in a natural wine matrix are available from Spex CertiPrep. The company is reportedly accredited by UL DQS for ISO 9001 and accredited by A2LA for ISO 17025 and ISO Guide 34. Spex CertiPrep, Metuchen, NJ;

GC–MS system

Shimadzu's GC–MS-QP2010 SE standard gas chromatograph–mass spectrometer is designed with an ion optical system that has a high-performance quadrupole mass filter. According to the company, maximum column flow up to 4 mL/min allows users to select from a variety of columns. Shimadzu Scientific Instruments Inc., Columbia, MD;

Gas chromatographs

Bruker's Scion Series gas chromatographs are designed with a data acquisition speed of >600 Hz per channel. According to the company, the instruments include a 9-in., multilanguage touch-panel designed for GC operation in 13 different languages. Bruker Daltonics, Billerica, MA;

Mass spectrometer

Thermo Fisher Scientific's Q Exactive high-performance benchtop quadrupole–Orbitrap mass spectrometer is designed to identify, quantify, and confirm trace-level metabolites, contaminants, peptides, and proteins in complex mixtures in one analytical run. According to the company, high confidence results are obtained without sacrificing MS-MS sensitivity, mass resolution, or quantitative reproducibility. Thermo Fisher Scientific, Billerica, MA;


Shimadzu's AXIMA Mega TOF system combines the company's linear MALDI-TOF mass spectrometer with a CovalX high-mass detection system. According to the company, the system detects macromolecules up to 1500 kDa. The system reportedly is also equipped with a conventional detector for samples less than 20 kDa in mass. Shimadzu Scientific Instrments Inc., Columbia, MD;

Mass spectrometers

AB Sciex's 4500 series of mass spectrometers is intended to be used for routine quantitation and screening. According to the company, the triple-quadrupole and QTRAP versions are designed to be "workhorse" mass spectrometers. AB Sciex, Foster City, CA;

Syringe filters

Thermo Fisher Scientific's Titan3 and Target2 single-use syringe filters for sample preparation are designed to accommodate greater burst pressures. According to the company, the filters are available in a range of filtration membrane types and porosities. The filters reportedly have a housing design that prevents leakage during filtration. Thermo Fisher Scientific, Waltham, MA;

Ion-trap GC–MS systems

Agilent Technologies' model 220 and 240 Ion Trap GC–MS systems are designed with the multiple ionization and scan modes of an ion-trap mass spectrometer and the capillary flow technology of a gas chromatograph. According to the company, the model 240 has MS-MS and MSn capabilities and can perform EI, CI, and MS-MS in the same run. The model 220 reportedly is designed for educational laboratories and laboratories needing rugged operation for high-throughput routine testing. Agilent Technologies, Santa Clara, CA;

Sorptive extraction

The EG-Silicone Twister device for stir-bar sorptive extraction from Gerstel reportedly combines ethylene glycol and silicone in the sorbent phase. According to the company, the device can extract analytes from sample volumes as large as 200 mL, and further sensitivity may be enhanced in multidesorption mode by desorbing multiple devices for each GC–MS run. Gerstel, Linthicum, MD;

MS system

PerkinElmer's AxION 2 TOF MS system is designed for mass identification and quantification for improved water quality and safer pharmaceutical and food products. According to the company, the analyzer is available with a choice of ion sources, including dual-probe Ultraspray 2 ESI or field-free atmospheric pressure chemical ionization. PerkinElmer, Waltham, MA;

Analytical UHPLC column system

The cartridge-based EXP analytical column system for UHPLC instruments from Optimize Technologies is designed for routine use at pressures as high as 20,000 psi. According to the company, the column holders are available in in-line and direct-connect formats. Optimize Technologies, Oregon City, OR;
