Twin interface analyser boasts sensitivity for trace elements
A twin interface is featured in the Spectrogreen TI ICP-OES analyser from Spectro Analytical Instruments. It is the latest version of the Spectrogreen inductively coupled plasma optical emission spectrometry (ICP-OES) analyser. The TI (Twin Interface) automatically combines both axial and radial plasma views to look both across the plasma and from end-to-end which optimises sensitivity, linearity and dynamic range while avoiding matrix effects like easily ionisable elements (EIE), says Spectro Analytical Instruments. The Spectrogreen TI is claimed to offer the highest sensitivity for trace elements, as well as freedom from matrix interferences and accuracy for challenging environmental matrices.
The Spectrogreen TI is the third version of the Spectrogreen compact mid-range ICP-OES analyser. It is designed for an array of routine laboratory analyses.
The other two models are the Spectrogreen DSOI which has a radial dual side on interface (DSOI), claimed to provide twice the sensitivity of conventional radial views and equalling the sensitivity of newer vertical-torch dual-view systems. There is also the Spectrogreen SOP, which has a dedicated radial, single side on interface for stability and precise performance where the added sensitivity of the DSOI is not needed.
All three analysers analyse elements — trace as well as higher concentrations — in organic, high salts, and metal samples. The cost-efficient analysers save on consumables with no-purge UV-PLUS and require no added cooling — eliminating the need for expensive, breakdown-prone external chillers.
Additional features include Orca optical technology that maximises light throughput, stability, and sensitivity. Spectrogreen’s transparency and light throughput provide a best-in-class performance for UV elements, and a DSOI model, delivering twice the sensitivity of a conventional radial view across the whole spectral range, says the company. The instrument offers access to the entire wavelength range via a single analysis, with no need to choose a viewing mode or make multiple analyses.
The analyser’s GigE readout system significantly boosts spectra processing and transport speeds for faster analysis, shorter sample-to-sample times, and more samples per hour. The thermal stabilisation of the optical system is achieved without sub-zero cooling. The analyser’s optimised spectral range CMOS line array technology avoids blooming while providing a fast readout and a wide dynamic range. The LDMOS 1700W generator helps analyse difficult sample matrices in lower dilutions to lower limits of detection while staying cool and with a fast warm up.
