Frequently Asked Question
Calibration frequency depends on the manufacturer’s guidelines, but many devices require daily or per-use calibration to ensure accurate results.
Routine maintenance includes cleaning electrodes, replacing reagent cartridges, checking calibration, and ensuring proper sample handling. Some models have automated maintenance functions.
Most analyzers are designed to work with whole blood, serum, plasma, or urine. However, it's important to check the device’s specifications for compatibility.
It typically means the ion-selective electrode needs cleaning, replacement, or recalibration. Refer to the user manual for specific steps.
Reagents have expiration dates specified by the manufacturer. Once opened, they may have a limited shelf life, so always store them according to the recommended conditions.
