  • Sample digester with independently controllable sample temperature and ultraviolet irradiation
    Patent number: 9086349
    Abstract: A sample digester with independently controllable sample heating and ultraviolet radiation. There are two unique advantages. Because the two digestion means are independent, the user can optimize the means of digestion to suit the analytical method. A second advantage is that the ultraviolet source can be maintained at a relatively cool temperature, for which the greatest amount of light is transmitted. Since both means of digestion can be carried out simultaneously, there is a substantial saving of time and a significant improvement in digestion efficiency.
