Refrigerant analyzer and a method of using the same

A method of detecting impurities in a refrigerant utilizing a refrigerant analyzer, wherein the refrigerant analyzer includes an electrochemical sensor operably coupled to a control device, the electrochemical sensor including a counter electrode disposed within an atmospheric regulated chamber and a sensing electrode disposed within a sensing chamber, the method comprising the steps:

• circulating conditioned air through the sensing chamber for an initialization duration of time to obtain an initial output value;
• determining whether the initial output value is stabilized below a pre-determined initial limit;
• circulating a refrigerant through the sensing chamber for a sensing duration of time;
• operating the control device to measure a sensed output value;
• and
• operating the control device to determine a measured concentration of at least one contaminant within the refrigerant based on the sensed output value.
