Agilent has launched its 6546 quadrupole time-of-flight (Q-TOF) liquid chromatography–mass spectrometry (LC/MS) system, which lets analysts acquire high-resolution data across a very wide dynamic range. According to Agilent, the instrument’s data-independent Q-RAI (quadrupole-resolved all ions) acquisition mode reduces the complexity of tandem MS spectra while maximizing the accuracy and quality of the data acquired. The MassHunter Quantitative Analysis 10.0 software includes features that allow laboratories to quickly and accurately screen complex sample sets for target and suspect compounds in a single workflow. Applications for the new LC/Q-TOF include metabolomics research, environmental screening, and food testing. Agilent Technologies Inc, 5301 Stevens Creek Blvd, Santa Clara, CA 95051,

According to Impedans, its Moduli RF spectrometer is the first instrument to allow users to directly monitor the electrical state of a plasma from outside the plasma chamber without modifying their plasma tool. The radio emission spectroscopy tool can be placed outside the plasma source—for example, at a window port or near a turbo pump. It can detect air leaks, wafer displacement, and other serious plasma faults in real time. The antenna is split into two parts, so the antenna pickup can go within the RF shielding and the amplifiers outside. The radio antenna collects the electric and magnetic waveforms from the chamber and sends them to the acquisition unit, which extracts the RF harmonics. The harmonic spectrum is very sensitive to small changes in plasma impedance, a key indicator of process repeatability.

ParticleScout, a particle analysis tool for WITec’s alpha300 Raman microscope series, delivers an accelerated workflow while making use of confocal Raman imaging’s abilities in fast, label-free, and nondestructive chemical characterization. It surveys samples with bright- and dark-field illumination to view the particles in them. Optical images facilitate the creation of a mask used to categorize particles of interest and arrange them in a ranked list. A Raman spectrum is automatically acquired from each particle and the spectra evaluated. The particles can be identified manually or by using the integrated TrueMatch Raman database software. According to WITec, the integration of a particle analysis tool with a Raman database is unique in the industry. ParticleScout is suitable for use in such fields as environmental science, geology, and microplastics and pharmaceuticals research. WITec GmbH, Lise-Meitner-Str 6, D-89081 Ulm, Germany,

The versatile mix-and-match components in Edmund Optics’ Techspec multielement tube system let users prototype and create uncommon optical designs. The system combines multielement outer tubes with multielement inner single and pair optic mounts. The outer tubes have M29 threads running down their entire length; inner mounts have M29 threads along their outer diameters, so they can be placed anywhere within an outer tube. The design allows for infinitely adjustable optical spacing along the optical axis. To ease adjustment, a custom-designed multielement tube spanner wrench has a hollow bore to let a beam pass through. The system can be further customized using spacer rings and tubes, inner apertures, and additional accessories. It accommodates circular optics with diameters from 5 mm to 25.4 mm and edge thicknesses up to 17 mm. System lengths, which can range from 15 mm to 100 mm, can be combined to expand capabilities.

The Pebble VIS OEM spectrometer from Ibsen Photonics combines an ultracompact form factor with high resolution, high sensitivity, and environmental ruggedness. At Pebble’s core is an efficient transmission grating manufactured by Ibsen: It makes possible a resolution of 6 nm across the full 380- to 850-nm-wavelength range. According to the company, that is among the highest for this size spectrometer. Pebble uses a fast, sensitive CMOS detector array with 256 pixels. When combined with a large numerical aperture of 0.22 (low f-number of f/2.2), Pebble provides very high sensitivity for a small spectrometer. Pure transmission-based optics ensure a very good thermal stability. Pebble is suitable for use in handheld and portable spectroscopy instruments for applications such as fluorescence and color measurements.
