5 Running the Instrument
Perform Daily Operational Checks 5.1
To ensure that your 2500 Analyzer is operating properly, perform the Membrane Integrity and Linearity checks on a daily
basis before running samples.
5.1.1 Enzyme Membrane Integrity Test
Run YSI 2363 Potassium Ferrocyanide (FCN) Standard as a sample to determine if your enzyme membranes are
structurally intact.
1. Pour a small amount of FCN standard (1000 mg/dL) in a test tube or multi-well plate.
2. From the Run Batch tab, touch [New].
3. Choose from the selection of supported racks and plates.
4. We highly recommend renaming the rack/plate “Daily Checks” by touching its ID to indicate that it contains your
daily check batches.
5. After selecting your plate/rack, touch the [Edit] button
6. Touch the location of each sample for the first batch. Selected locations will be blue.
