The SC series of high-voltage power supplies introduced by Applied Kilovolts is the first in a generation of fast-polarity switching modules for mass spectrometers.
These high-performance source supplies have been designed to meet the needs of high-throughput mass spectrometers.
Featuring Tru-Current technology with control at the APCI source and fast-polarity changeover in less than 10ms, the modules are suitable for multi-mode source applications where changeover, settling time and precise current control are all critical.
Available from Applied Kilovolts' Brandenburg division as constant-current or constant-voltage types, they are designed for electro-spray ionisation and atmospheric pressure chemical ionisation sources.
'By reducing the process time for each batch through the mass spectrometer, the rapid switching speed allows increases in throughput, giving users an improved return on investment,' said Mark Williams, Applied Kilovolts' marketing director.
For corona-source applications (constant-current mode), the minimum controllable current is 2uA.
All the models are also available with switching times of less than 50ms.
Output is said to be highly stable, with ripple of less than 0.1 per cent p/p and drift (after a one-hour warm-up) of 100ppm per hour.
The modules are true-zero volt-crossing and short-circuit and flashover proof.
A fully screened metal case is intended to provide good EMI immunity.
