Certified Liquid Standard for Laboratories

Analyser calibration mixtures for refineries and petrochemical plants.

Liquid hydrocarbon mixtures for laboratories and research

Mixtures of liquid components and low volatile liquified gases can’t be produced as a gaseous reference material due to a much too low pressure and risk of condensation. In such case, the Certified Liquid Standards has the solution.

Typical application is found in refineries, cracking installations to monitor the proces streams of f.e. raw materials like propylene, 1,3 butadiene, aromates, and all hydrocarbons with vapour pressures below 2 bar at 0°C.

Certified Liquid Standard

Available in cylinder sizes from 3, 10 and 50
liter watercapacity.

Cylinders are equipped with a 2‑way valve Gas & Liquid.
The gas side can be used to connect an assist gas to
pressurise the liquid mixture inside the cylinder
(ideally helium because of its low solubility in hydrocarbons).

“

The liquid side of the valve is connected to a dip-tube inside the cylinder to easely withdraw the liquid mixture to your analyser system.

The Certificate will clearly indicate which
method has been used.

These standards are certified by composition
(gravimetric weighing), by laboratory analysis
or by a combination of both. These standards
are not suitable for highly volatile components
such as e.g. ethylene or permanent gases such
as methane.
