Setting new standards in vessel inside vessel technology We introduce the best of vessel-inside-vessel solutions to ensure lower analytical blank during microwave digestion in modern laboratory. This configuration reduces the amount of acid required for digestion to near stoichiometric quantities which provides lower dilution factor to increase detection limit Increase detection limit with lower dilution factor Microwave digestion techniques typically require a...

Think Pure.  Reagent contaminations increase the background concentration of the analytes present in a sample. Because of this, laboratories purchase expensive high-purity acids for trace metal (element) analyses.  With small samples sizes it is critical to keep blank levels low for good reproducibility.  There is an alternative to the purchase of expensive high purity acids: Milestone has developed the DuoPUR and...

Think Blank.  Cleaning various items used in ultra-trace analysis work is a critically important laboratory routine. Milestone has developed the traceCLEAN, a fully automated, selfcontained, acid steam cleaning system for trace metal analysis accessories. Place the items to be cleaned in the traceCLEAN system, program the time and temperature required, then press “Start”. Freshly distilled acid vapors will continuously reflux within the...

Think Pure.  The Milestone subCLEAN is a compact and easy-to-use sub-boiling system, where all parts in contact with acids are made of high-purity fluoropolymers. The subCLEAN is therefore suitable for the purification of HF, as well as for HNO3 and HCl. SUB-BOILING TECHNOLOGY The chemical reagents used during the analysis are an important source of the analytical blank. Sub-boiling distillation has been demonstrated to be...
