In addition to the “simple routine samples”, many users also need to process the most challenging sample materials. For this target group, devices are required that are both powerful and meet the highest safety requirements. In this context, the all-rounder Speedwave Xpert shines thanks to its new SafePrep concept. The use of 2 magnetrons with a total of 2000 W power significantly increases performance, enabling digestion of the most difficult sample materials. At the same time, the microwave is equipped with dynamically regulated fans which provide a marked noise reduction during digestion in comparison with similar models.

The Kjeldahl method KjelDigester reduces the block digestion process by up to two hours and meets the highest safety requirements. The high degree of automation is the perfect match to the KjelMaster System allowing for unprecedented sample throughput. Applications includes classical Kjeldahl tasks such as TKN (Total Kjeldahl Nitrogen) or Devarda as well as the direct distillation of other volatile components such as alcohol, sulfur dioxide …

Our custom designed QAsh software allows the user to make batch fi les that control all aspects of an ashing process. The samples are ramped or held steady at specifi c temperatures in multiple steps as a function of time according to easy-tomake batch fi le program. Further, the blower motor and fl ow of air to the sample are both under the control of software. This way, precise, reproducible ashing of samples is possible from day to day. All sample ashing data is collected and stored in hard disk for archiving or future viewing in graphical or tabular formats. Several different batch fi les may be made in order to accommodate the varying types of user sample types. If desired, the sample program can be modifi ed at any time, even during running.
