The participation fee for GAS2009 is € 880,- (excluding VAT). Registrations before 1 December 2008 will receive an early-bird € 100,- discount. More information is available in the brochure of GAS2009. If you are interested in giving a scientific presentation or a lecture on new developments for the users in any of these fields, please contact the organization. Speakers will be asked for an abstract. All speakers are given a discount on the participation fee and of course they take part in the best-lecture contest.

Invitation ACQUAL

Participants in GAS2009 are invited to submit manuscripts related to their presentations (either lectures or posters) for a topical issue of Accreditation and Quality Assurance (ACQUAL). Please read more in the invitation.

Seminar on Gas Correlation Schemes

Adjacent to GAS2009 a seminar on LNG and Refinery Gas Correlation Schemes (GCS) will be organised on Tuesday 10 February and Wednesday 11 February. GCS is a worldwide interlaboratory correlation scheme on LNG and refinery gas. On Tuesday and Wednesday morning the participants of GCS will have a closed meeting to exchange experiences. For Wednesday afternoon, when also GAS2009 commences, some lecturers related to GCS are planned in the session on natural gas and LNG. This topic might also be of interest in other sessions. Combining those events will create added value for both the participants of GCS and participants of GAS2009.
