Gas Chromatography – Time Of Flight – Mass Spectrometry

This service is temporarily unavailable

Description

GCT mass spectrometer with an analyzer time of flight of orthogonal acceleration and high resolution (FWHM ~ 7000), equipped with four sources of ionization.

When coupled with a gas chromatograph is used to analyze mixtures of volatile and semi-volatile compounds, using three different modes of ionization: electron impact (EI), chemical ionization (CI) and field ionization (FI).

The relatively pure samples may also be introduced directly into the ionization source with a probe. The latter mode allows for direct analysis of samples using four modes of ionization, EI, CI, FI and field desorption (FD).

Equipment

GC-TOF-MS (Gas Chromatography - Time Of Flight - Mass Spectrometer) Micromass, model GCT.

Sample

Solid and liquid samples are analyzed. They are dissolved in the solvent indicated by the client in concentrations of the order of ppm or ppb depending on the molecular weight of the sample and the desired mode of ionization.

Price analysis

Note: 1) Figures do not include VAT. 2) The urgency rate is three times the value of the table. 3) Analysis with direct introduction of sample (except FD) exceeding 30 min has a value plus 40%. 4) The simultaneous application of more than 8 samples for the same type of analysis has a 5% reduction.

Analysis Request

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. In the case of samples for method development and in the case of large number 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.
