Introduction to the instrument

LH-XRF rock element analyzer is an optical instrument that analyzes the element content of samples such as cores, cuttings, borehole wall cores, and field outcrops at the logging site. This instrument uses the content of each element in the rock and its derivative parameters. Lithology analysis can be performed, and curve reports can be formed.

The instrument has fast analysis speed, high test accuracy, good repeatability, strong stability, small size, light weight, flexible operation, and is suitable for on-site logging conditions.

Main technical parameters:

1, elemental analysis range: sodium (Na) to uranium (U)

2, 35 elements can be analyzed at one time;

3, element content analysis range: 1ppm-99.99%

4, pipe pressure: 5KV-50KV

5, pipe flow: 50uA-1000uA

6, energy resolution: 135±5eV

7, measurement time: <600s;

8. Relative deviation: <10%;

9. Repeatability: <10%.

Advantages:

★The lithology analysis of volcanic sedimentary rocks can be carried out;

★With plate analysis, curve analysis, approach analysis and other lithology recognition functions;

★Provide element data statistical parameters, support custom design of analysis chart;

★Can flexibly control data import and export;

★Custom parameter design can be carried out;

★The report can be designed in various forms;
