Introduction
The Berghof Speedwave Xpert is the latest model microwave digestion system that provides faster digestion with higher sample throughput.
Sample batches can be turned around quicker with a booster extraction fan configuration that is 20% more efficient. Each vessel safely vents excess pressure to a common manifold ensuring acidic vapour does not corrode the microwave internals.
The new vessel design includes no metals components to ensure high quality digest for trace level analysis. The vessels incorporate the latest high temp. composite material for vessel longevity.
The Xpert continues the successful use of TFM-PTFE for vessel fabrication. This unique material is custom formed in a hydrostatic bath such that there is no axial weakness in the material. The higher density TFM vessel has better properties with regards to temperature, pressure and acid resistance. Importantly while conventional PTFE has an affinity to adsorb small levels of digested material into the structure, the higher density, hydrostatic TFM-PTFE shows no accumulation in the vessel with time, making it ideal for mercury digests for low level analysis by ICP-MS. TFM-PTFE conforms to EPA Hg digestion standards.
There is also no need for special acid wash cycles of the vessels between digests.
The new model includes the unique features of the previous model with the two temperature sensors and a pressure sensor in each vessel cap monitoring all vessels without cable connections. An additional safety feature has been added to monitor vessel surface temperature as well as internal sample temperature on all vessels. This leads to longevity of vessels and caps and extended warranty.
An extensive library of applications allow Sanautomatic download of a suitable method for digestion.
All of these advanced features mean the Speedwave Xpert microwave digestion instrument can digest more difficult samples at higher pressures and temperatures (100bar and 300 deg C) in a safer manner.
The successful vessel design with a high diameter/ depth ratio ensures that sample gets to the bottom of the vessel with minimum spoilage on the vessel walls. Vessel ID is a generous 27mm.

Measures
Both sample temperature and vessel temperature are monitored to provide the most accurate transient conditions during the microwave process.
A unique design allows individual vessel temperatures to be measured with each carousel rotation.
