Our Products
Analyser & Sampling Systems
At every point where hydrocarbons are processed, transferred, or distributed, obtaining a truly representative sample from the process line is critical, for quality assurance, custody transfer, regulatory compliance, and process optimisation. Our Analyser and Sampling Systems are engineered to withdraw, condition, and store representative samples of liquid, gas, or condensate with precision and integrity, while minimising time-lag, sample contamination, and emissions to atmosphere.
We supply two complementary categories of systems: Product Sampling Systems for composite and grab sampling of hydrocarbons in pipeline applications, and Process Analyser Systems for continuous online analysis of process streams and utilities.
All systems are custom-engineered to client specifications and can be designed as skid, rack, cabinet, or shelter-mounted installations. Manual, automatic, open-loop, and closed-loop configurations are available, with full compliance to applicable international standards.
Product Sampling Systems
A product sampling system is designed to capture and combine thousands of individual incremental samples taken from a flowing pipeline into a single, statistically representative composite sample for laboratory analysis. Correct system design is essential, errors introduced by cold spots, dead ends, or improper phase management at any point in the sample chain will compromise the integrity of the final result.
Gas Sampling For natural gas and light hydrocarbon gas streams, isokinetic sampling principles are applied to maintain sample composition throughout the collection and handling process. Pressure and temperature are controlled throughout to prevent condensation and composition changes that would otherwise alter laboratory results.
Condensate Sampling For high-pressure condensate streams, onshore or offshore, systems are designed to minimise the effects of process fluctuations and phase change. Condensate sampling and mixing systems comply with ISO 3171, ASTM D4177, API 8.2, and IP 6.2 for custody transfer, fiscal, allocation, and quality measurement applications.
Crude Oil Sampling Automatic crude oil sampling systems are designed for reliable allocation, custody transfer, and BS&W measurement in accordance with international sampling standards. Typical configurations include stainless steel heated enclosures, grab sample pumps, bypass vanishing chamber samplers, and auto-switchover mechanisms for duty and standby sample containers.
Refined Product Sampling For diesel, gasoline, naphtha, aviation fuel, and other refined products, sampling systems are designed to produce representative samples from which quality and density can be rapidly analysed, supporting the issuance of a Certificate of Quality.

Process Analyser Systems
A process analyser system extracts a representative sample from the process stream, conditions it to the correct pressure, temperature, and phase, and delivers it to an online analyser — continuously and with minimum time-lag — to support real-time process control, product quality monitoring, environmental compliance, and safety.
Every component in the sample conditioning chain is a potential source of error. System design must eliminate cold spots, dead ends, and holdup points that could cause sample degradation, phase separation, or delayed response. Our process analyser systems are engineered end-to-end to ensure the sample delivered to the analyser is representative of the process at all times.
