Formerly, a well-known and world-recognized Praxair (Thailand) Co., Ltd. Our accredited laboratory was established since 1997, after meagered with Linde (Thailand) Plc. In 2020, we relocated to new facility in PTT Gas Separation Complex-Rayong and name it as “Linde Laboratory” operating under Linde (Thailand) Public Company Limited.
Linde accredited laboratory is a certified ISO/IEC 17025:2017 and listed in approved analytical Laboratory service of major international bottlers and food industry to analysis gases supply for instant, CO2 feed gas, CO2 product, and Nitrogen product. Our new laboratory service has extended scope of certified to analysis industrial gas products of H2, CO, O2, N2, and Ar.
Our Laboratory service is equipped with state-of-the art technologies and expert in gas quality testing to a wide range of customers with international standard requirements (ISBT) and the major international bottlers requirements.
