The GERDA is a great tool at any stage of mineral exploration! It can work right at the drill site or in base camp, which incredibly increases your efficiency.

GERDA – Geochemical Research and Documentation Assistant – is an automated sampler for portable and handheld analytical instruments such as pXRF, NIR spectrometers, magnetometers, etc.

The GERDA can be used for:

• assaying drill core right in core boxes;
• assaying stream sediment/soil samples in field bags;
• assaying RAB, RC drilling chip samples;
• determination of gold mineralization in crushed rock/drill core samples utilizing NEFFA method;
• assaying any 2D flat objects like paintings and etc..

EASY SAMPLER PXRF TEST STAND BY OUR AUSTRALIAN DISTRIBUTOR WILTEC

Available models are compatible with either Olympus Vanta or Thermo Fischer Niton pXRF’s.

Many other manually operated pXRF test stand products exist, however, they all have the same basic design flaws, and the same operational limitations to productivity when users need to accomplish hundreds (or even thousands) of assay tests.

• The pXRF is docked in underneath the test rig.
• The sample cups then must be inserted upside-down so that the material in the cup doesn’t fall out.
• The test rig can only load one sample cup at a time.

With Wiltec Solutions’ Easy Sampler, these operational limitations have now been solved
