Microwave digestion with top-loading concept for very simple handling and a high sample throughput
Berghof speedwaveŽ four
In many analytical laboratories today microwave digestion is a standard method of preparing samples for determining elements. For microwave digestion the sample material is typically heated to 200 - 260°C in closed microwave-transparent pressure vessels with an acid mixture and thereby fully degraded and dissolved. The advantage of microwave digestion compared to conventionally heated stainless steel pressure digestion vessels lies in the accelerated heating-up phase and the possibility of simultaneous digestion of multiple samples. However, the economic efficiency of the overall system is determined less by the number of samples per run than by the handling costs and the working hours required for it. This finding was consistently taken into account in developing the Berghof speedwaveŽ four microwave digestion system. The speedwaveŽ four distinguishes itself by simple handling and low operating costs...

Pressure Digestion for Sample Preparation
What analyst does not wish for a universal method for processing all his or her samples? Pressure digestion represents just such a procedure for sample digestions and is therefore one of the standard sample preparation procedures currently employed in analytical chemistry for element quantification...

Reaching the Next Level of Microwave-assisted Organic Synthesis
Microwave-assisted organic synthesis (MAOS) has become an increasingly popular discipline in modern chemical method development. At first, reaction optimization and method development on a small scale were the main areas of interest in MAOS. However, the growing acceptance and success of this innovative microwave technology revealed the necessity for large-scale synthesis of valuable compounds using microwave heating, especially in industrial laboratories...

A Platform System for Microwave Sample Preparation
Multiwave 3000
Today's technology enables the near-perfect determination of trace elements in all concentrations down to the ultra trace range. Modern AAS, ICP-OES, ICP-MS or electrochemical procedures such as voltammetry are reliable and accurate measuring methods for almost every type of task. However, in most cases the sample material has to be supplied in a suitable, measurable form, i.e. as a largely matrix-free solution without contamination or loss of analytes...
