Gas generators have become an alternative to high-pressure gas cylinders for supplying laboratory applications with high purity hydrogen, nitrogen, and zero-air. Until now, there has been no generator option for supplying high purity oxygen. Small pressure swing adsorption (PSA)-based oxygen generators are available for medical applications but do not offer the high purity generally required in the laboratory.

Problem: Bringing samples into a mineralized state is usually the first step for performing accurate inorganic analysis, aka metals trace analysis. This conversion of a usually non-homogenous insoluble mixture into a representative, homogenous aqueous solution using heat and acids is usually a prerequisite for further analysis work with spectroscopic or chromatographic techniques.

Reviews and appraisals can be a very helpful tool for employees and organizations to achieve better results
