Real-time elemental analysis for prompt process control

There are several tasks which require prompt data on the chemical composition of the analyzed material, e.g. analysis of geological samples, core samples, drilled dust and sludge.
Geological samples:
We offer a mobile laboratory, which consists of a crusher (grain size from 50mm to 2-3 mm) with a conical sample separator (which ensures high degree of representativity of the sample) and a laser express-analyzer with a rotating table where samples weighting less than 5 kg can be placed; this is usually enough to ensure that the sample with a 2-3 mm grain size is representative. No special drying is necessary. Most importantly, the surface of the sample should not be covered with clay, snow or ice; 10-15% moisture level does not prevent the analysis in any way.
Core samples:
We offer an express-analyzer with a 2-axes table, which ensures that the whole surface of the core could be analyzed. This kind of mobile analyzer can be place on any pickup truck or a van; it does not require a high precision sample preparation (either simple crushing or cutting of the core suffices) and can provide results of the analysis within several minutes of the sampling.
Drilling dust and sludge:
We offer LIBS analyzer which can be placed right on a drilling rig.
The cost of this kind of analysis is many times less expensive than the cost of conventional tests.
Please contact us for more information about the express laboratories.

Currently, there are three methods of analysis of geological exploration samples, of cores and drilling solids:

  • in a stationary laboratory, where samples are delivered after the geological exploration. In this case one can only get the results of the analysis long after sampling. This method requires labor-intensive sample preparation made by highly qualified personnel.
  • in mobile laboratories, which are made of expensive crushing, drying, grinding, compressing and XRF analytical equipment. Drying of a large volume of crushed samples (which in case of a grains size of several mm should be several kg for every sample) should be done before grinding and compressing; this is very time consuming. Grinding and compressing require high accuracy; XRF analysis requires highly qualified personnel who follow the x-rays safety guidelines, which is often very difficult under field conditions. Moreover, a mobile lab of this kind should be equipped with a very expensive all-terrain chassis.
point analysis, which is performed with hand-carried manual analyzers, either XRF, spark-based, or laser-based. In this case, it is basically impossible to ensure that the analysis is representative because the results depend on the choice of the analyzed points and vary depending on how well the selected points represent the whole mass of the analyzed mineral.
