Distillation testing device

With the MICRO DIST system from Lachat Instruments, you can now distill up to 21 samples for cyanides, sulfide and ammonia in 30 minutes; and phenolics and tritium in 90 minutes. USEPA-approved QuikChem® methods for the determination of several chemical species in environmental samples have been used for several years with the QuikChem Automated Ion Analyzer. Based on the techniques of flow injection analysis (FIA), these methods provide rapid, accurate and precise determinations. However, for some analytes samples must be taken through a complicated and time-consuming distillation process to remove the analyte from a potentially interfering matrix prior to automated analysis. As a result, the analyst is required to use a low-throughput, large-volume manual distillation method involving classical vaporization, condensation, and collection with expensive and fragile macro-scale glassware. This is incompatible with the productivity features of high-throughput automated analyzers. In response, Lachat has developed the MICRO DIST system. This system distills 21 samples simultaneously in convenient, disposable or recyclable polypropylene tubes. The most popular applications are the distillation of cyanides and total recoverable phenolics. Both solid and liquid samples can be digested and distilled.
