ChromaCalGas

£1.00

Gas Chromatography is a powerful technique used to separate and analyse the composition of a specific gas sample. ChromaCalGas has been designed to provide you with a reliable analysis benchmark to compare with readings of LNG gas onboard a vessel and therefore calculate it’s calorific value.

 

Benefits:

  • Custom Gas Mixtures: Ensures precise measurements and reliable reporting.
  • Compliance & Verification: Helps confirm adherence to charter party agreements and regulatory standards when running journeys on LNG fuel.
  • Optimised Cylinder Design: Maintains stability in transit and storage, preventing over-pressurisation.
  • Reliable, On-Time Delivery: Dedicated account managers ensure a seamless ordering process.

The Standard for Accuracy

ChromaCalGas is a specialist gas mixture designed to calibrate Chromatography systems. Chromatography is widely used in industries such as pharmaceuticals, forensics, environmental monitoring, and the energy sector to separate and analyse gas components. Our gas mixture ensures that these systems are effectively calibrated, and therefore provide the most accurate readings possible, making it an essential tool for dual-fuel LNG vessels reliant on Chromatography system to calculate the calorific value of the LNG being used as fuel.

We supply a standard ChromaCalGas mixture in a 50L liquid bottle with a BS4 valve, we are also capable of offering bespoke mixtures where required.

Standard Mixture


This standard mix has been carefully designed to provide a reliable analysis benchmark, ensuring accurate fuel assessment. With an accuracy of +/- 2%, you can confidently compare your bunkered fuel’s composition to our standardised gas mixture.

Custom Mixture


While our standard ChromaCalGas mixture is the ideal choice for most dual-fuel LNG vessels, we understand that some operators may require tailored gas compositions. If your vessel has specialised Chromatography requirements, we offer bespoke gas mixtures to match your specific needs.

Frequently Asked Questions

What is ChromaCalGas?

ChromaCalGas is a highly specialist gas mixture designed to calibrate Chromatography systems. Chromatography is a process by which components of a mixture are separated and analysed. This process is widely used by industries such as the pharmaceutical, forensic, environmental and energy sectors.

Why would I need ChromaCalGas?

Chromatography systems are becoming more widely used worldwide, along with the rise of LNG-powered vessels. Having a Chromatography system on board a dual-fuel vessel means that that vessel can measure and analyse the composition of any natural gas it takes on board and therefore calculate its calorific value (how much is required to produce enough power to get from point A to point B). ChromaCalGas is specially formulated to ensure that these systems can be calibrated effectively to provide an accurate reading.

This is especially important for those vessels bound by charter-party agreements and reliant on accurate predictions of fuel consumption on their registered journey.

Why does Martek Marine have a Standard Mix for ChromaCalGas?

The purpose of ChromaCalGas is to give you a reliable analysis benchmark to compare with readings of your LNG fuel on board. You can be assured that our standard ChromaCalGas mixture is accurate to +/- 2%, so by using the readings obtained from analysing our ChromaCalGas, and comparing the results to the fuel you have bunkered, you can reliably ascertain the constitution of the fuel you will be using and therefore calculate its calorific value.

What is the difference between a ‘Certificate of Analysis’ (COA) and the information on the label?

The information on the label of the cylinder summarises exactly what you ordered; the Certificate of Analysis (COA) is the result of analysis of what is in the cylinder. This means that the list on the certificate of composition is what is actually contained within that specific cylinder.

What is the difference between tolerance and accuracy?

Accuracy on the certificate of conformity is the term used to describe the degree to which these measures can be relied upon. For example, if during analysis the analytical instrument gives a result of 20.4%, then due to the accuracy of +/- 2% the cylinder can hold a concentration between 20.0% and 20.8%. Tolerance is the permissible range of variation of a gas percentage from its nominal value. Tolerance is governed by what is practically achievable within the constraints imposed by man and machine when manufacturing the cylinder.
