New Spectrometer Offers Higher Acquisition Speed for Light Measurement
Using the Power of Atomic Fluorescence Spectroscopy for Ultimate Detection Performance
Coupling Atomic Fluorescence Spectroscopy (AFS) with either cold vapour generation or hydride generation has been PS Analytical’s (PSA) core competency for over 30 years.
For the determination of mercury, arsenic, selenium, antimony and bismuth, PSA offers some of the best laboratory instrumentation available. The instruments are typified by their small footprint, ease of use, good reliability and robustness, as well as having affordable purchase and running costs.
PSA works with many industries, organisations and markets to deliver industry leading analysers. The systems are used to analyse waters, soils, sediments, air, stack gas, blood, urine, food and beverage, petrochemicals, polymers, minerals and many other sample matrices.
Ocean Optics has upgraded its Ocean FX miniature spectrometer to now offer an acquisition speed of up to 4,500 scans per second, high-sensitivity CMOS detector performance and integration times as low as 10 µs. With fl exible features to manage saturation intensity, it is suitable for high-intensity LED and light source measurement, laser characterisation, spectral analysis of rapid events and plasma monitoring.
Depending on the performance of the operating system to which it is connected, Ocean FX can acquire up to 4,500 scans per second. This speed allows users to collect more spectral information over shorter periods of time, contributing to better results. The high speed is also useful for capturing rapidly occurring modulation of light output, such as fl icker in LEDs and other sources (see Ocean Optics Application Note:
https://oceanoptics.com/ ocean-fx-high-speed-applications-in-home-lighting/). The powerful onboard processor holds up to 50,000 spectra in its memory and can perform averaging of up to 5,000 spectra, signifi cantly speeding up transfer times and reducing bandwidth requirements.
Ocean FX is anchored by a high-sensitivity CMOS detector that is responsive from 200-1,100 nm. To account for varying light intensity, its adjustable integration time ranges from 10 seconds down to 10 µs. This ability to integrate over much briefer periods - microseconds instead of milliseconds - avoids saturating the detector in even extremely high-intensity applications. Ocean FX’s interchangeable slits give users the ability to further adjust for differences in light source intensity.
Users can operate the Ocean FX via Gigabit Ethernet, Wi-Fi, USB and now SPI communication protocols. The addition gives OEM users greater design flexibility, eliminating the need for cables or additional circuitry to convert signals. Ocean FX is available in versions optimised for the UV-Vis (200-850 nm), Vis-NIR (350- 1,000 nm) and extended (200-1,025 nm) wavelength ranges. Enhanced-sensitivity, custom and OEM configurations are also available.

PSA analysers provide excellent detection performance including ultra-trace limits of detection, a linear response over several orders and minimised interferences from other matrix components. PSA’s unique flow cell design, removes troublesome glass or quartz material and results in reduced carryover for faster throughput and less re-runs.
The instruments are ‘speciation ready’ with easy coupling of chromatographic systems to our ultimate performing analysers.
With literally thousands of systems in the field today, and support networks in Europe, USA and SE Asia, PSA offers the ideal package of performance, reliability and support. For further information visit

Near-infrared Spectroscopy for more Effi cient Product Quality Control in Manufacturing Industries
Metrohm is pleased to offer turnkey solutions for the quality control of commodities such as diesel, gasoline, jet fuel, polyols, palm oil, and wood pulp by Near-Infrared Spectroscopy (NIRS). Based on dedicated spectral databases and a pre-calibration models, these solutions enable manufacturers to reduce the cost of their daily routine analysis while improving the quality of their products.
Key quality parameters for the above mentioned commodities are still often determined by time consuming physical or wet chemical methods involving complex sample preparation.
NIRS, on the other hand, is a non-destructive analytical technology that requires neither chemicals nor sample preparation, it can even be used by non-chemists, and provides results in less than a minute. Furthermore, multiple chemical and physical parameters can be determined simultaneously with a single measurement. The combined benefits of this technology make NIRS the ideal solution for a large number of daily QA/QC measurements or continuous process analysis. Metrohm offers pre-calibrations for the following products: gasoline, diesel, jet fuel, polyols, palm oil, wood pulp.

New Single Quadrupole Mass Spectrometer and Specialised Columns Designed to Deliver Reproducible and Robust Separations, Increase Analytical Accuracy
Thermo Fisher Scientifi c Inc has announced new technologies that are designed to allow analytical chemists to obtain high-resolution separations with outstanding sensitivity and reproducibility.
“Our customers want gain a deeper understanding of their samples,” said Mitch Kennedy, Vice President and General Manager, Life Sciences Business, Chromatography and Mass Spectrometry, Thermo Fisher.
The new Thermo Scientifi c ISQ EC Single Quadrupole mass spectrometer seamlessly integrates with an existing ion chromatography (IC) or high performance liquid chromatography (HPLC) system and provides excellent small molecule sensitivity and mass confi rmation for users. The industry-leading Chromeleon Chromatography Data Software (CDS) platform has embedded ISQ EC MS instrument control, which enables users to minimise time spent on new mass spectrometry (MS) user training. The instrument also provides exceptional robustness, enabling users to analyse a range of simple and complex sample matrices.
The new range of Thermo Scientifi c MAbPac RP 1mm columns, which are designed to provide the resolution and ruggedness required for high-performance, reversed-phase chromatography characterisation of monoclonal antibodies, fragments, variants, antibody drug conjugates and proteins. With a 1mm inner diameter, the new columns provide sensitive analyses of very small sample volumes at low fl ow rates for direct injection into the LC-MS, thus streamlining workfl ows and achieving high sensitivity. Featuring a polymeric resin with an optimised pore size and thermal and pH stability, the new columns allow consistent and effi cient separations with low carry-over.
