Isotopic Ratio Mass Spectrometerdelta S Finnigan Mat

The finnigan mat delta s is dedicated to stable carbon isotopic δ13c analyses having been extensively modified to provide high sensitivity.

Isotopic ratio mass spectrometerdelta s finnigan mat.

The isotope ratio measurement is calibrated based on repeated measurements of nbs 19 and nbs 18 and precision is 0 10 for d18oand 0 08 for d13c 1sigma. The isotopic composition of the samples was measured against a working standard gas. Up to 10 collectors in a wide range of configurations supporting all isotope ratio ms applications in the mass range up to m z 96. Supplies and service for the mat 253 sector isotopic ratio ms.

Carbon isotope compositions were analyzed with a combined gas chromatography combustion isotope ratio mass spectrometer delta s finnigan mat. The finnigan mat 251 is a magnetic sector isotopic ratio ms. In order to aid you in the selection of replacement parts for your instrument the following part number cross reference chart can be used. Contact sis about parts and repair services for the mat 251.

Scientific instrument services carries a wide selection of parts for all models of thermo finnigan mass spectrometers. Available preconcentrators elemental analyzers gc interfaces lc interfaces and continuous flow inlets. The gc utilizes a septum equipped programable injector spi and is also fitted with a ctc a200s autosampler. The uncertainties of 3 he 4 he ratio r r atm 4 he 20 ne ratio and helium abundance are 1 10 and 10 respectively.

Simultaneous mass range up to 25. Isotopic compositions of carbon in teeth and claws were determined by combustion of the samples in an elemental analyser carlo erba 1108 finnigan mat bremen germany interfaced with an isotope ratio mass spectrometer delta s finnigan mat bremen germany. Powdered samples were reacted with dehydrated phosphoric acid under vacuum at 70 c. δ13c values for compounds with typical abundances of 5 ng are determined routinely.

Isotope ratio mass spectrometers have also helped laboratories in the fields of food and doping analysis providing trustworthy analytical results. Samples hc2 hc5 and hc8 were too enriched in18otobe 2. Browse our complete portfolio below or let one of our experts help you tailor a selection specific to your application and workflow needs. Leaf carbon isotope composition δ 13 c leaf was expressed relative to the pee dee belemnite standard vpdb and the analytical precision was 0.

To a gas ratio mass spectrometer finnigan mat 252. The isotopic analyses were conducted using a finnigan continuous flow isotope ratio mass spectrometer delta s finnigan mat bremen germany at the stable isotope facility at inra nancy france.
