6.7 Daily Operational Checks
To assure that your SPORT is operating properly, check the membrane integrity
and the linearity every day.
We recommend that you keep an instrument logbook in which dates and lot
numbers of reagents are recorded, along with a record of daily operational
checks and other relevant information.
Membrane Integrit Membrane Integrit Membrane Integrit Membrane Integrity Test y Test y Test y Test
Use YSI 2363 Potassium Ferrocyanide (FCN) to determine if your membranes
are intact. This solution is packaged in your starter kit, and may also be ordered
separately. With the instrument in SAMPLE mode, inject 25 microliters of the
solution with whichever injection device was used for calibration.
The reading should be below 0.3 mmol/L (2.7 mg/dL). If it is greater, repeat the
test. If it's still too high, change the membrane.
Linearity Test Linearity Test Linearity Test Linearity Test
Use YSI 1530 30 mmol/L or YSI 2328 15 mmol/L Lactate Standard to check the
linearity of the sensor. These standards are packaged in your starter kit, and also
may be ordered separately.
Acceptable Ranges:
YSI 2328 YSI 2328 YSI 2328 YSI 2328 14.30 to 15.70 mmol/L (128.3 to 141.7 mg/dL)
YSI 1530 YSI 1530 YSI 1530 YSI 1530 28.50 to 31.50 mmol/L (256.5 to 283.5 mg/dL)
