INTERNATIONAL PLANT-ANALYTICAL EXCHANGE
METHOD INDICATING CODE (MIC)
HOW TO USE THE MIC FORMS:
*
the MIC should be reported only once;
*
use the MIC registration form on page 5 and/or 6 for reporting you MIC;
*
always fill in your code name and code number;
*
always fill in the starting date of the MIC codes;
*
fill in the element and corresponding element number (see form for results);
For inorganic chemical composition (use page 5):
*
fill in the code for the used digestion and extraction technique (table 1.1);
*
fill in the used method of detection (table 1.2);
*
always fill in the starting date of the MIC codes;
For nutritional parameters, vitamins and amino acids (use page 6):
*
fill in the code for the used pretreatment (table 2.1);
*
fill in the used method of extraction (table 2.2);
*
fill in the code for the used separation technique (table 2.3);
*
fill in the used method of detection (table 2.4);
*
always fill in the starting date of the MIC codes;
*
sent this form always by surface mail even when you use fax or E-mail because sometimes it
is problematic to get clear readable documents.
Example
You indicate behind the element Cd under method of digestion/ extraction the code DB, and under
method of detection the code BC. This example means that for the determination of Cd in plant
material in your laboratory a wet digestion technique without HF is used and that the final medium is
HNO3 ; for the detection of Cd the AAS-ETA with Zeeman background correction is used.
