Determination of mineral components in dry plant materials by laser elemental analyzer LEA-S500

(dry leaves, fodder, dry biofuel, tea, tobacco, etc.)
Elemental analyzer LEA-S500 can be used successfully for solving biochemical and agrochemical tasks

The technique developed by the specialists of SOL instruments allows to carry out measurements of 22 elements in dry leaves, fodder, mixed fodder, dry biofuel, vegetable crops, vitamin-mineral complexes and other objects.

Lower detection limits of most elements amount to ppm, detection limits for some elements amount to fractions of ppm. Expressivity of the method, minimal sample preparation provide wide possibilities for environment monitoring, including plant objects and food.

Samples with already known chemical composition can serve as calibration samples, availability of CRM or standard samples of a manufacturer allows of careful control of measurement accuracy.
