From sample to result

1. Sample: Representative aggregate sample, refrigerated or processed immediately, labelled with batch and silo number.
2. Grinding: At least 90% passes through a 20-mesh sieve. Coarser grinding substantially increases variance.
3. Weigh: 50,0 ± 0,2 g into an extraction bag or vessel.
4. Extract: Water with WET powder or 70 % methanol, depending on the strip; shaking time according to protocol.
5. Dilute: First dilution for the normal range, second for high levels.
6. Incubate and read: Strip into the reader, 2 to 10 minutes, followed by automatic reading. The result is sent directly to EZ Receiver.

What the reader records — and where it goes next

For each measurement, the reader stores test ID, sample ID, operator, temperature, date and time. During the run, it also checks the sample volume, whether the strip has already been used, whether the lens requires cleaning, and whether the door remained closed during incubation. The reader's memory is not a quality system. That is what EZ Receiver is for: every result is received via the network, checked against the product limit, approved with an electronic signature, and sent as a single file to your LIMS.

What the system does not do

The EZ-M system is a screening and quantifying instrument. It is not a confirmatory technique and not an accredited reference method. For a formal rejection, a dispute or an official control, LC-MS/MS or HPLC with validated performance characteristics remains necessary. The instrument also does not replace sampling: a poor sample produces an accurate number for the wrong grain.
