Question
What is the purpose of the Air Gap Assembly for Ammonia ISE electrodes?
Summary
Reason to use the Air Gap Assembly.
Answer
The Air Gap Accessory optimizes performance and extends the usable lifetime of the membrane module. Samples containing substances known to cause membrane failure (e.g., surfactants, oils, and fats) can be measured repeatedly with this accessory. Slopes, absolute mV readings, and response times may change significantly when the Air Gap Accessory is used. Therefore, use the Air Gap Accessory for all calibrations and Measurements.
