Gas Chromatography-Flame Ionization Detector

Description

GC-FID samples (approximately 1microL) are introduced into the injector through a syringe. The sample is drawn by the mobile phase (carrier gas) along the column. By applying a temperature ramp program the different components of the mixture are separated. These compounds elute from the column dissolved in the carrier gas pass through FID detector where they will undergo pyrolysis at the flame temperature, of air by the action of the H₂, producing ions and electrons which conduct electricity through the flame.

The GC-FID can be used for the analysis of volatile organic compounds or semi-volatile compounds such as hydrocarbons, pesticides, PAHs, fatty acids, higher alcohols, essential oils, solvents, etc ...

Equipment

GC-FID (Gas Chromatography - Flame Ionization Detector) Konik, model Konik HRGC 4000B.

Sample

Liquid samples are analyzed in concentrations of the order of ppm, or samples pre-concentrated in fiber (SPME).

Price analysis

 Note: 1) Figures do not include VAT. 2) The urgency rate is three times the value of the table.

Request Analysis 

The analysis request should be filled and signed by the head of the institution that makes the request (Download the application form). Analyses are performed by order of submission of application in laboratory analysis. The results are given within 24 hours. In the case of samples for method development and in the case of large numbers of samples, the response time is agreed with the authority solicitor.

The equipment is operated solely by the technician in charge. If requested by the client it is allowed direct contact with the equipment which provides a brief technical/theoretical accompanied demonstration working practice.

Upon request of an analysis the client should contact the technician directly responsible for the equipment to clarify all issues that involve the analysis.

Delivery and receipt of samples

1 - Samples must be clearly identified, so that during manipulation does not erase the identification, and should be delivered well packaged.

2 - Delivery of results will be made by e-mail in PDF format, to be sent simultaneously to the applicant and responsible. In the case of complaints, they should be made within 15 working days.

3 - The remainder of the samples will be stored in the laboratory for 15 days after completion of the analysis, after which will be eliminated.
