# Analysis of total hydrocarbon residues (HCT) by GC-FID

## Manufacturers of medical devices, you want to analyze the total hydrocarbon residues (HCT) in the framework of the ISO 19227 standard

### What is a hydrocarbon?

A hydrocarbon is an organic compound (synthetic or natural) composed exclusively of carbon (C) and hydrogen (H) atoms. Produced by the distillation of petroleum, a hydrocarbon is a member of the family of persistent organic pollutants.

There are two types of hydrocarbons: 

- saturated hydrocarbons: whose carbon chain is made up only of single bonds (e.g. alkanes)
- unsaturated hydrocarbons, whose carbon chain has at least one double or triple bond (e.g. alkenes)

In addition, hydrocarbons are present in many different products, including

lubricants
detergents, etc…

### Why analyze your medical devices by GC-FID?

[Gas chromatography with FID detector](https://filab.fr/en/our-technical-resources/gas-chromatography-analysis-lab-gc/gc-fid-analysis-laboratory.md) is a technique for separating a mixture of volatile and semi-volatile molecules. Thus, it is a method that allows the analysis of different compounds of a mixture and an evaluation of health risks.

Indeed, the analysis of hydrocarbons is part of the control parameters because their presence can present a certain toxicity for the man.

Moreover, the analysis of total hydrocarbon residues (TCH) allows to adapt the cleaning process. Indeed, HCT contamination can have various sources, in particular during :

- the manufacture of the medical device
- its handling,
- packaging and storage 

Thus, the support of a laboratory accredited [COFRAC ISO 17025](https://filab.fr/en/about-us/accreditations-en/laboratory-analysis-iso-17025.md) on the analysis of HCT and specialized in the analysis of medical devices is an essential asset for the evaluation of the cleanliness of your medical devices.

## FILAB supports you in the analysis of total hydrocarbon residues (HCT) by GC-FID

The FILAB laboratory can assist you in the analysis of total hydrocarbon residues (HCT) on medical devices and equipment according to the ISO 19227 standard (formerly NF S94-091), using validated and documented methods.

Thus, our experts are at your disposal and offer you their analysis services for HCT cleaning residues.
