38  LMS  Issue 2 | 2014 Product Review A New Evaporation/Concentration System on the Horizon H orizon Technology, a leading global supplier of automated sample preparation systems for the analysis of organic compounds and oil and grease testing, has introduced the XcelVap™ system. The XcelVap is an automated benchtop evaporation/ concentration system that provides rapid and gentle evaporation of up to 54 sample extracts, ranging in size from less than 1ml to 200ml. Liquid/liquid, continuous micro or solid phase extractions of environmental, food, clinical or other matrices need evaporation of the solvent to rapidly reduce sample volumes appropriate for the best analytical instrument sensitivity. Evaporation is accomplished by combining consistent heat, controlled sparge gas and active venting of the solvent vapours. With the XcelVap, less time and attention is required to prepare reproducible extracts for chromatographic analysis (GC/MS, LC/MS, GC, LC), improving laboratory productivity. The XcelVap features: • Automated pressure profiling for optimum speed with the most reproducible recoveries • Nozzles can be individually changed by the user, simplifying maintenance and reducing operating costs • Easy water bath management with water-level sensor and front draining for best performance • Up to 54 samples can be processed • • • • simultaneously for unprecedented productivity Accommodates a number of popular sample tubes providing flexibility for multiple applications Reliable unattended operation, freeing the operator for other tasks Small footprint and portrait orientation maximises space inside fume hoods or on the lab bench Fumes are exhausted through a rear vent po
