TOF mass spectrometers
The Xevo G2-S QTof and Xevo G2-S Tof benchtop time-of-flight mass spectrometers from Waters are designed with the company's StepWave ion optics and off-axis ion source technology. According to the company, the systems are as much as 20× more sensitive than earlier-generation instruments and critical components stay clean longer. Waters Corporation, Milford, MA;
Purification method scouting software
The Method Toolbox software from Shimadzu is designed to assist with method optimization. According to the company, the software allows chemists to analyze up to 96 methods, 16 mobile phase solvents, and six columns, all in one batch. Shimadzu Scientific Instruments, Columbia, MD;
UHPLC injector
VICI Valco's Cheminert C72 ultrahigh-pressure UHPLC injector is designed with a stator coating that permits pressures up to 15,000 or 20,000 psi. According to the company, the instrument is available in four-, six-, eight-, and 10-port configurations, with a bore diameter of 0.004, 0.006, or 0.010 in. Valco Instruments Company, Inc., Houston, TX;
Pesticide analysis system
The PesticideScreener system from Bruker is designed for multiresidue analysis of pesticides in food and feed. According to the company, the system includes UHPLC and QTOF-MS hardware, applications software, and LC–MS methods. The system also includes a database that includes retention times for the matched UHPLC method; adduct information; isomer information; fragment ion information; isotopic confirmation; and qualifier ions for "one-shot" confirmation in broadband MS-MS mode. Bruker Daltonics, Billerica, MA;
Mass selective detector
The Agilent 5977A series GC mass selective detector reportedly has a redesigned inert MS ion source that enhances performance with efficient ion collection. According to the company, the detector uses the company's TwisTorr 304 FS turbomolecular pump, which is optimized for light gas operation. Agilent Technologies, Santa Clara, CA;
Sample preparation–LC system
Thermo Fisher Scientific's Prelude SPLC sample preparation and liquid chromatography system is designed to work with the company's mass spectrometers, automating sample preparation and increasing throughput. According to the company, the system has two channels of HPLC separation, and it is capable of gradient operation at flow rates of 1–2000 μL/min. Thermo Fisher Scientific, San Jose, CA;

Photodiode-array detector
PerkinElmer's Flexar photodiode-array detector is designed to provide a wide detection range, low baseline noise, wavelength accuracy, and a fast data acquisition rate. According to the company, the detector is suitable for tandem use with other detectors and is compatible with third-party chromatography data systems. PerkinElmer, Waltham, MA;
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;
Getting accurate IR spectra on monolayer of molecules
April 18th 2024Creating uniform and repeatable monolayers is incredibly important for both scientific pursuits as well as the manufacturing of products in semiconductor, biotechnology, and. other industries. However, measuring monolayers and functionalized surfaces directly is. difficult, and many rely on a variety of characterization techniques that when used together can provide some degree of confidence. By combining non-contact atomic force microscopy (AFM) and IR spectroscopy, IR PiFM provides sensitive and accurate analysis of sub-monolayer of molecules without the concern of tip-sample cross contamination. Dr. Sung Park, Molecular Vista, joined Spectroscopy to provide insights on how IR PiFM can acquire IR signature of monolayer films due to its unique implementation.
