Mass Spectrometry & Spectroscopy 19 Reliable Autosampler for UV/VIS and NIR Sample Loading


Have you got an UV-Visible/NIR Spectrophotometer in your lab? Are you tired to load manually your samples one by one? Do not worry: your half days - or even full days - boringly spent in sample acquisition are over. You can now take advantage of the defi nitive solution for the automation of optical spectroscopy analysis, the HT1500U from HTA Srl that allows to fully automate the sample loading into UV-Visible/NIR Spectrometer.


The automation will bring the undoubted convenience of delegating the manual sample loading, but also undeniable advantages especially in terms of analytical results: you will experience consistent increase of productivity, gain in analysis robustness and even minimisation of the carry-over.


The on-board solvent reservoir allows for the probe and the whole fl ow path to be cleaned before processing the next sample, with the option to program the number of washing cycles according to the sample physical and chemical properties. Furthermore, sample replicas and calibration curves will be executed more often as the whole process is carried out unattended.


HT1500U is available in multiple confi gurations: it supports stainless steel as well as polymeric needle to deal with metal sensitive applications, and a wide choice of fl uidics to deal with different sizes of fl ow through cells, including nano fl ow through cuvettes, micro cuvettes as well as macro cells. Different kinds of tubes are supported too: open or sealed tubes can be hosted to fi t any applications. The tubes are organised in multiple racks - each of them removable - to allow continuous sample feeding and more convenient operation.


Regardless of the application you are running, the HT1500U will meet and exceed your expectations in terms of quality and reliability, requiring no or minimal training.


The automation of you UV-Visible/NIR Spectrometer requires just a preliminary step to make the spectrophotometer suitable for automation by HT1500U: the standard quartz cell/cuvette must be replaced with a fl ow cell. This fl ow cell will be then fully handled by HT1500U and all the samples will be automatically processed. No additional action is required: you can go away and return just for the post-production data management.

New LC-MS Workstream for Targeted Toxicology Analysis Launched


The new Thermo Scientifi c Tox Explorer Collection offers a comprehensive LC-MS workstream for toxicology assays. The Tox Explorer Collection consists of proven and tested methods enabling toxicology laboratories to achieve accurate, high-resolution data, regardless of analyte type, matrix complexities or user expertise. The Tox Explorer Collection consists of a comprehensive library of analytes, allowing for faster identifi cation and targeted screening assays with 1,500 compounds confi rmed in a single analysis. The Thermo Scientifi c Tox Explorer Collection is compromised of the following components: Thermo Scientifi c Q Exactive Plus Hybrid Quadrupole-Orbitrap mass spectrometer; Thermo Scientifi c Vanquish Flex UHPLC system; Thermo Scientifi c TraceFinder software; Thermo Scientifi c Accucore column and consumables confi gured for high performance; an extensive HRAM mzVault library of 1,500+ compounds and database with streamlined data processing and reporting; proven method comprising critical hardware parameters along with a step-by-step walkthrough guide for quick start-up and method installation; application support and training.


“Toxicology laboratories must ensure they carry out reliable, reproducible and sensitive analyses with a quick turnaround, using numerous instruments and software to ensure thorough sample screening,” said Brad Hart, Senior Director, Clinical Research, Chromatography and Mass Spectrometry, Thermo Fisher Scientifi c. “The Thermo Scientifi c Tox Explorer Collection provides a robust, consistent, all-in-one LC-MS workstream, with an extensive library of analytes to allow for high-performance, targeted analyte screening on a daily basis.”


Simon Hudson, Technical Director at LGC, said: “As a sports anti-doping testing laboratory, we look for a user-friendly and accurate means of testing samples at a high throughput, without compromising results. The Thermo Scientifi c Tox Explorer Collection provides us with an easy-to- implement workstream, consisting of a selection of toxicology solutions to facilitate targeted screening and quantifi cation. We can, therefore, confi dently achieve an outstanding quality of data, allowing LGC to stay competitive as an anti-doping analysis provider.”


To accompany the Tox Explorer Collection, Thermo Fisher Scientifi c offers a strong customer support network, comprising a comprehensive training and application support package. The package is coupled with a complete start-up guide that includes installation and method instructions. The collection also includes a complete portfolio of services and support solutions from Unity Lab Services, Thermo Fisher Scientifi c’s single source for integrated lab service, assistance and supply management.

Confi dence in Compliance with UV-visible Spectroscopy CRMs


Starna Scientifi c is the world’s only supplier of Certifi ed Reference Materials for UV-visible spectroscopy to be accredited to ISO 17034:2016, the international benchmark for reference material producers. Users of their CRMs can therefore be confi dent that compliance measurements will be to the highest possible standard and accepted by regulatory authorities worldwide. This accreditation, and the ISO/IEC 17025 accreditation of Starna’s calibration laboratory, covers a unique range of spectroscopy reference materials for wavelengths from the deep UV to the mid infra-red. Starna Green, for example, is a novel, non-toxic (REACH compliant) absorbance CRM usable from 250 nm to 650 nm and at absorbance values up to 5 A. Instrument users therefore have an the widest possible choice when selecting CRMs to match their analytical conditions, as required by the latest editions of the pharmacopoeias. The Starna range also includes references for microvolume measurements, microplates, fl uorescence and life science applications.

New Peristaltic Pump for Atomic Spectroscopy Announced


Since German scientists Robert Bunsen and Gustav Kirchhoff have discovered that the colour of a fl ame changed once an element was introduced, atomic spectroscopy has developed into one of the most successful analytical methods, which is applied every day worldwide and routinely. Among the different methods in atomic spectroscopy both multielement methods ICP-MS and ICP-OES have been extremely successful for the analysis of liquids. For transport of the liquid sample peristaltic pumps are well established to overcome any change in the composition leading to changes in viscosity thus reducing matrix effects. The material for the elastic tubing can be selected depending on the chemical properties of the analyte solution, so that even strong acids or organic solvents can be transported. However, sometimes signal pulsations are observed with very sensitive devices, so that they need to be reduced by manually optimising the pressure of the pressure plate. Such an optimisation is not required any more for a new generation of pumps. It is based on the ‘easy click’ principle, where the pressure of the plate is adjusted already by a spring, so that no manual optimisation is needed any more, and the analysis sequence can be started immediately.


In an investigation of the Bundesanstalt für Materialforschung und -prüfung (BAM) in Berlin, Germany, Spetec has tested two different peristaltic pumps and the ‘Easy Click’ pump operated on a simultaneously measuring ICP-OES instrument, to see whether or not any difference of the analytical fi gures of merit can be observed (the whole report is available on request). This investigation had demonstrated that all analytical fi gures of merit including limits of detection (LOD) and signal stability of in total ten elements (Al, Bi, Co, Cr, Cu, Fe, Mg, Mn, Ni, Se) from a standard solution do not differ signifi cantly for all tested pumps. The resulting LODs measured are in the lower µg/L range and standard deviations of less than 1% for eight and less than 2% for the remaining two elements have been achieved.


As a fi nal result Spetec can say that the ‘Easy Click’-pump can compete with the two reference pumps concerning the analytical fi gures of merit but excels with easy and fast changing of tubing without any further adjustment.
