Abstract
Nitrate-delta(15)N from groundwater samples is determined on an inorganic nitrate derivative using automated, continuous-flow elemental analyzer/isotope ratio mass spectrometry (EA/IRMS). Nitrate is extracted and concentrated based on a recently published ion-exchange resin method. Freeze-dried AgNO(3) (0.5-1.5 mg) is packed in silver-foil cups and combusted within the reactor of an NC2500 elemental analyzer (CE Instruments, Milan, Italy) using its existing reaction scheme for nitrogen and carbon analysis. delta(15)N is determined using a Finnigan MAT DELTA(plus) isotope ratio mass spectrometer (Bremen, Germany). Results are drift-corrected to a AgNO(3) working standard that has been calibrated against known AgNO(3). Despite high concentrations of carbonate, the precision for all runs is better than 0.10 per thousand. The combination of this extraction procedure with commercially available delta(15)N analysis instrumentation offers a precise on-line alternative to existing methods, with considerable reduction in labor and analysis time.

Abstract
A method for the automated sample conversion and on-line oxygen isotope ratio (delta(18)O) determination for organic and inorganic substances is presented. The samples are pyrolytically decomposed at 1400 degrees C in the presence of nickelized graphite. With the system presented organic as well as inorganic samples such as nitrates, sulphates and phosphates of 50-100 &mgr;g O can be analyzed for their delta(18)O values with a standard deviation usually better than 0.5 per thousand. Additionally, carbon isotope ratios of organic substances and nitrogen isotope ratios of inorganic nitrogenous compounds are available in the same sample run. Data for international and some inter-laboratory reference materials are presented to show the accuracy and reliability of the method. The effect of some additives on the CO yield was checked for substances which do not pyrolyze completely. Copyright 1999 John Wiley & Sons, Ltd.
