How often should I clean my digestion vessels? What are some common mistakes to avoid when cleaning digestion vessels? What are the steps involved in cleaning a digestion vessel? Learn how to reduce sample prep contamination by an effective cleaning of items used in ultra-trace analysis

Purify your own HF, HNO3 and HCl acids with the Milestone subCLEAN system is the smarter choice for your lab. Low cost, low grade acid is automatically loaded into the distillation container where it is gently heated below its boiling temperature using a sub-boiling technique. High purity acid vapours rapidly condense into a collection bottle by forced air cooling meaning that no chiller is required either.

The analytical instrument is just one component in achieving the lowest limits of detection using plasma spectrochemistry. The other critical area that puts significant demands on a laboratory’s overall detection capability is to ensure that the sample preparation procedure does not contribute any additional sources of contamination.

New paper publication titled "Evaluation of recycle and reuse of nitric acid from sample digests by sub-boiling distillation" has just been published on Microchemical Journal. In short, the article shows that acid digestion waste can be recycled (through a sub-boiling purification process) and reused, without compromising the quality of the analytical results, with clear benefits in costs and for the environmental health.
