The Company has an analytical laboratory that meets high-performance requirements and ensures the quality control of the products delivered, helps to identify the contamination of the products and allows to provide the customers with the highest quality analysis of refrigerants:
- Identification of impurities
- Identification of substances such as HCFC / HFC / HFO
- Determination of concentration of compounds
- Analysis of the quality of isobutane, propane and other saturated hydrocarbons
- Determination of non-condensing gas in the gas phase
- Identification of recycled materials according to technical specifications
During rectification, we can separate the mixed freons into components, while simultaneously performing regeneration.
HOW IS A PRODUCT ANALYSIS CARRIED OUT?
Upon agreement with a customer, a 1000 ml aerosol cylinder is prepared (cleaned and vacuumed). It comes with a hose which is connected to the system’s service valve. The filling is carried out only in the liquid phase of the refrigerant.
A customer can deliver a bottle with a sample either himself or through a courier service. The minimum amount of product needed for analysis is 100 - 150 grams.
If the customer wishes to establish the moisture content of the freon, strict requirements for sampling are applied. It is necessary to ensure that moisture does not reach the surface of the hose or service valve at the time of sampling. Any presence of condensation may distort the results.
Two types of detectors are used for product analysis: thermal conductivity detectors (TCD detectors) and flame ionisation detectors (FID detectors). Saturated hydrocarbons are highly flammable, and therefore a flame ionisation detector is used for chromatographic analysis. This is a particularly sensitive and precise method that allows determining the amount of material with an error of 0.01%. Thermal conductivity detectors are used for the analysis of simple HFC, HCFC and HFO refrigerants.
The results of a chemical analysis may, if necessary, be provided to a customer within an hour. The customer not only receives a chromatogram but is also familiarised with the information contained in it.

Upon receiving the results of chemical analysis and identification of the changes of the refrigerant, it is recommended that the client should deflate or replace the refrigeration agent.
HOW CAN A PRODUCT ANALYSIS BE USEFUL FOR YOUR BUSINESS?
The composition of the materials used for refrigeration must comply with the ASHRAE standards; therefore, if there is a chance a product might be affected, a chemical analysis must be carried out. The changed composition does not allow to reach the required temperature; therefore the energy consumption can increase. In addition, non-condensing gas may occur in the gas phase of the freon, which also affects the normal operation of the system and the increase in energy costs.
Therefore, chemical analysis is a quick way to establish potential threats before they hinder the system’s operation. This extends the life of the system and protects against costs that can occur in the event of a severe failure of the system.
