On-line monitoring for improved wastewater system management: applications of ultraviolet/visible spectroscopy
To ensure that the removal and treatment of our sewerage meets increasingly high standards, it is important to be able to monitor the water online both to provide timely information and also to establish changing patterns over days, weeks and seasons. In their article “On-line monitoring for improved wastewater system management: applications of ultraviolet/visible spectroscopy”, Rita Brito, Rita Ribeiro, Tatiana Arriaga, Catarina Leitão, Nìdia Lourenço, Filipa Ferreira and Helena Pinheiro demonstrate the value of on-line UV/vis spectroscopy for wastewater quality monitoring in decentralised wastewater treatment and for spectral on-line monitoring of key quality parameters at the inlet to wastewater treatment plants.

Automated detection of counterfeit drugs using multimodal spectroscopy and advanced web-based software platforms
In the Tony Davies Column, we learn about “Automated detection of counterfeit drugs using multimodal spectroscopy and advanced web-based software platforms”. With the increase in trafficking of counterfeit medicines and other products, there is a need for definitive results from an on-site analyser useable by customs officers. The German authorities have commissioned the development of a multi-modal, transportable inspection system, including intelligent data processing and evaluation, for fast spectroscopic recognition of illicit drugs and counterfeit medicines. This is described in the column.
Monitoring of catalytic reactions and catalyst preparation processes in liquid phase systems by combined in situ spectroscopic methods
In situ spectroscopic methods such as infrared, Raman and UV/vis spectroscopy are powerful tools to gain insight into reaction mechanisms and catalyst actions in homogeneously catalysed reactions. These methods and combinations of them offer great potential for the real-time monitoring of reactions in the liquid phase, for mechanistic studies as well as process control and kinetics.
Range of OEM spectrometers in UV, Vis and NIR versions, with resolutions down to 0.2 nm in the UV, 0.4 nm in the Vis and 0.6 nm in the NIR and a size of 61 × 64 × 19 mm. The series incorporates Ibsen’s high groove density master transmission gratings which are made from pure fused silica.
A special configuration of the V-700 series of UV/Vis/NIR spectrophotometers with a monochromator with automatically exchanged dual gratings: 1200 lines/mm for the UV/Vis; 600 lines/mm for the NIR. A PMT detector is provided for the UV/Vis and an InGaAs photodiode detector for the NIR. Both gratings and detectors are automatically exchanged within the user-selectable 800–900 nm range with higher resolution settings with enhanced sensitivity in the NIR.
Miniature spectrometer that provides high thermal stability and low unit-to-unit variation whilst maintaining flexibility and configurability. Fully configurable over the 190–1100 nm wavelength range. Features such as interchangeable slits, indicator LEDs and simpler device connectors are included. It has a footprint of 89 × 63 × 34 mm and weight of 265 g.
First Ocean Optics’ spectral device to use a solid-state optical encoder instead of a diffraction grating. Wavelength range is 380–700 nm and available in both OEM and standalone versions, it is suitable for simple absorbance, fluorescence and emissive colour measurements. A range of Spark accessories, including clip-on cuvette holders, diffusers and light sources is compatible with both versions.
Multi-purpose UV/vis spectrophotometer with wavelength scanning from 190 nm to 1100 nm along with intuitive operation, enhanced validation, maintenance and inspection functions. It has seven measurement modes including photometric, spectral, kinetics, DNA/protein and multi-component quantitation. USB flash drives can be connected to the instrument to transfer analysis data.

The new Genova Plus life science UV/vis spectrophotometer is now available from Jenway. With dedicated modes for DNA/RNA analysis, pre-programmed methods for protein analysis plus standard spectrophotometer functions, the user-friendly system is optimised for applications in biochemistry, forensic science, genetics, biotechnology and other life science laboratories. Based on the Jenway 73 series, this new instrument incorporates a large graphical display built into the lid of the unit. Icon-driven software and soft-key navigation ensure fast analysis and ease of use. A large internal memory enables over 300 methods to be stored and, for added convenience, results and methods can be saved to a USB memory stick. In addition to dedicated modes for DNA/RNA analysis, protein assays, nucleic acid purity and optical density, the system can also be used as a standard spectrophotometer with measurement modes for photometrics, concentration, multi-wavelength, spectrum scanning, quantitation and kinetics.
BioDrop, a microvolume cuvette from BioDrop, provides a robust and affordable approach to low volume spectroscopy. Its patent-pending design has the same dimensions as a conventional cuvette but is manufactured in two halves that are held together using two magnets. The precision machining ensures that the path length is accurate and its simple optical layout provides high-energy throughput ensuring accurate measurements over a wide dynamic range and only one path length is required for most experiments. It is easy to use, is robust enough to withstand the knocks and falls commonplace in laboratories and its ergonomic design makes it easy to handle, even with wet gloves. Available in 0.5 mm or 0.125 mm path lengths, it can be used to perform UV/vis spectroscopy on sample volumes as low as 1 µL, making it suitable for life scientists measureming DNA, RNA and protein samples.
High-throughput circular dichroism measurement system which automates CD and UV/vis absorbance measurements for large numbers of samples. A third detector option allows simultaneous fluorescence measurement. The flow system coupled with an ASU-800 autosampler provides precise micro sampling and eliminates complications often associated with automated CD measurements.
CW laser-driven Xenon light source for high power in the 170–2100 nm range. It works by focusing a 1000 nm laser through a Xenon bulb, creating a high-intensity plasma, which gives maximum output over a broad spectral range. For deep-UV operation there is optional purging.
