Thermo Finnigan Delta^plus

Continuous flow instrument using ConFlo II open split interface coupled to:

Carlo Erba NA1500 Series 2 EA

Carlo Erba NA1500 Series 2 Elemental Analyzer
Used for flash combustion analysis of organic matter from particulate matter on filters, plants, animals, and sediments. Interfaced with the Deltaplus via ConFloII open split for continuous flow analysis of primarily N and C isotopes and concentrations. S can be analyzed, but requires change in instrument configuration.

Typical precision of measurement:	< 0.15 ‰ for both N and C isotopes
	<1% for both N and C concentrations
Time required for analysis:	~10 minutes for both N and C
Cost per analysis:	$8.00
