Samples sieved through 2mm sieve are loaded into petri dishes. Each petri dish is labeled according to the sample serial number. 20g of each soil sample are loaded into the petri dishes. The petri dishes are arranged in a sequential manner in a trolley and they are transported to IR lab. For plants vials are used. When the samples are returned from the IR lab after scanning they are off-loaded by returning them into their packages and stored for archive. Petri dishes are wiped with a non-fluffy material to remove dust particles. Vials are washed with distilled water.
