SAMPLE PREPARATION

Automation is a key ingredient for establishing well-performing and flexible applications that can work in high throughput mode.
We recommend the MultiPurpose Sampler (MPS) from GERSTEL as a basis for automation in your lab.
This intuitive system can be adapted to your laboratory needs thanks to its modular design and works with any brand of GC or LC systems.
Its proprietary MAESTRO software is fully programmable and can also be integrated in other software packages, such as Agilent’s MassHunter platform.

We kick off with automated sample preparation for GC and GC-MS.
