56 SPECTROSCOPY
ICP-OES analyser with powerful generator S
pectro Analytical Instruments recently introduced its latest version of the Spectroblue inductively- coupled, plasma optical emission spectrometer (ICP-OES), updated with a powerful new generator that brings a new level of performance to routine laboratory analysis in industrial and environmental applications. The latest version of the analyser capitalises on more than 30 years of service by Spectro ICP-OES analysers. That heritage can be found in the Paschen-Runge optical system, which provides excellent optical resolution and sensitivity. The
new instrument also utilises UV-PLUS gas purification technology, as well as an OPI- AIR interface that avoids costly, complicated external water cooling. The new Spectroblue model brings
the latest plasma power to mid-range spectrometers. Its new laterally diffused metal oxide semiconductor (LDMOS) generator delivers up to 1,700W of power. Benefits include a faster warm-up time
for high productivity. While traditional tube- based generators take up to 30 minutes to stabilise after start-up, the Spectroblue analyser’s new solid-state generator allows the system to be ready to analyse in less than 10 minutes for most applications. It also features
excellent matrix compatibility. High power gives the instrument great agility in the case of rapidly changing plasma loads and provides for high matrix compatibility. Samples can be analysed in lower dilutions, for lower limits of detection. A further
advantage is the new
version’s longer lifetime. The new analyser is extremely robust and trouble free. Its innovative air-cooled system operates without external cooling, delivering low running costs. Unlike traditional power sources, the analyser’s new generator has no parts subject to wear - minimising time and expense. The spectrometer is available with three
versions of plasma interface, depending on its intended use. Spectrobule EOP’s axial interface provides high sensitivity and low detection limits, making it ideal for superior analysis of trace elements in industrial and environmental applications. Spectroblue SOP has a radial interface that is ideal when low detection limits are of less importance than accuracy and precision at higher sample concentrations. It is also well suited for analysing organic solutions and slurries. Finally, Spectroblue TI has a twin interface – automatic axial and radial plasma observation – that eliminates the EIE (Easily Ionizable Elements) effect. It provides accurate determination of alkali/earth alkali elements in a complex alkali/earth alkali matrix and is ideal for environmental applications such as analysing sodium, potassium or calcium in wastewater or soil matrices.

High resolution and sensitivity in one
he new AvaSpec-Hero from Avantes is designed for those who are in need of both high resolution and high sensitivity. The spectrometer combines the best of both worlds, including USB3 and Ethernet. With a higher aperture, a cooled back thinned detector and low noise, it’s the ideal instrument for demanding applications including: fluorescence, Raman, absorption and others. Based on high sensitivity compact optical bench (f=100mm; NA=0.13) and a 1024x58 backthinned CCD detector, it offers both sensitivity and resolution. The instrument is equipped with TE Cooling, enabling long integration times
