Overview of Laboratory Isotope Analysis Methods for Water Resources Studies

overviewProper preparation and analysis of isotope samples are essential for the interpretation and development of a sound assessment of water resources and potential water supplies. This DVD provides an overview of laboratory methods used for preparation and analysis of samples for deuterium and oxygen-18, carbon-13 and carbon-14, noble gases, tritium and CFCs. Many analytical details are covered allowing a view of individual analytical methods to gain an in-depth understanding about how to conduct isotope analyses in the laboratory. Watch the full tutorial.

LIMS for Lasers

LIMSThe IAEA Isotope Hydrology Laboratory (IHL) has partnered with the U.S. Geological Survey to develop a new Laboratory Information Management System (LIMS) for water oxygen and hydrogen isotopes analyses for users of laser absorption spectrographs. LIMS for Lasers is a user-friendly MS Access–based instrument and laboratory data management system for all off-axis (OA-ICOS) or cavity ring-down (CRDS) laser absorption spectrographs (LAS) used for δ2H and δ18O assays of water. This open-source database software will assist new and current users of LAS instruments to improve their laboratory productivity and QA/QC outcomes, and is available cost-free for all laboratories.

Key Features of LIMS for Lasers
Client project and sample data management and reporting system.
LAS instrument sample analysis templates.
Automated between-sample memory correction.
Automated instrumental drift correction and outlier checking.
Automated normalization of data to the VSMOW-SLAP scales.
Track My Lab QA/QC for instrument and laboratory assessment.
Excel sample submission templates.
Laboratory standard calibration templates
User Benefits
Increased staff productivity by eliminating Excel spreadsheets.
Improved long-term LAS performance through standardized approaches.
Reduction of laboratory error in client and data management.
Fast laboratory performance evaluation through use of QA/QC controls.
Compatibility with LIMS for Light Isotopes v.9x.
Laboratory Implementation
Ready-made instrumental databases allow running samples in hours.
Detailed instruction manual and tutorial included.

LIMS Data Viewer

LIMS Data ViewerThe IAEA Isotope Hydrology Laboratory (IHL) has partnered with the U.S. Geological Survey to offer LIMS Data Viewer, an optional companion utility to LIMS for Lasers that can be used in trusted teams, departmental settings, or laboratory group settings.

This utility allows network-connected laboratory clients (e.g. co-workers, colleagues, managers) to have read-only access to the LIMS for Lasers backend database from their desktops, but without any capacity to edit or alter information in the database.

Key Features of LIMS Data Viewer
View and extract current laboratory workload and client projects.
View their projects and analysis status.
Download or export their project data to Excel, or print a report.
Reduce need for phoning the laboratory concerning sample or project status.

FLOWPC (Ver. 3.2)

flowpcUse of Lumped Parameter Models for the Interpretation of Environmental Tracer Data in Groundwater Studies.

This software package and its complementary documents were developed as part of the Co-ordinated Research Project on 'Mathematical Models for Quantitative Evaluation of Isotope Data in Hydrology', which was implemented from 1990 to 1994. This application was developed by Prof. P. Maloszewski, GSF –Institute of Hydrology, Germany. Lumped parameter models are particularly useful for interpreting environmental isotope and tracer data in groundwater systems, especially when the isotope data is obtained at separate sampling sites, when it is neither possible, nor justified, to use distributed parameter models, as the latter require more detailed knowledge of the investigated system.

The application was originally developed in DOS but it runs under Windows. The application and the manual are available from the zip file. The latest version (3.2) of FLOWPC and selected examples, as well as input functions for stable isotopes and tritium are included in the zip file. The manual and the examples presented are based on reports describing the use of these models (Maloszewski and Zuber, 1996 and Zuber and Maloszewski, 2000).

Note to Windows 7 users: FLOWPC has been reported to start up correctly under Windows 7, but to cause a fatal exception after specifying input parameters and -files and before starting the actual calculations. We recommend to try an MS-DOS emulator to run FLOWPC under Windows 7, e.g. the open-source software DOSBox.

isogridIsotopic Gridded Rainfall Data Software

This application is an open source based utility used to generate gridded maps of stable isotopes (δ18O, δ2H) in precipitation. It was developed by Prof. A. Argiriou and V. Salamalikis from the Laboratory of Atmospheric Physics, Patras University, Greece within the framework of the Coordinated Research Project on 'Geostatitical Methods of Spatial Isotope Variability to Map the Sources of Water for Hydrology Studies'. The package uses a combined multiple regression/interpolation approach to generate gridded stable precipitation isotope maps.

ISOGRIDS is based on the R language and environment for statistical computing and graphics, which can be obtained freely under GNU General Public licence (GPL2) for Windows, Unix and Macintosh operating systems. Several additional libraries are necessary to run the application; these are listed in the software manual. The download package is a zipped file including scripts for manipulating deuterium and oxygen-18 values, a user´s manual, and a sample dataset. For working with and editing the script, a text editor is required, we recommend Tinn-R and, also distributed under the GPL2.

To run the application from the R console, just copy the scripts to the working directory (or change it using the setwd "YourDirectory" command), adjust the script according to pages 9 (Excel version) and 12 (custom models) in the manual and load/run the scripts individually (using source "manual_oxygen_18.r" or source "manual_deuterium.r"). After that, prompts will appear for any additional input required.

ISOGRIDS allows the use of different gridded climatic datasets and provides the possibility to use pre-defined as well as custom multiple regression functions and kriging or thin plate splines algorithms for the interpolation of residuals. Please refer to the tutorial for further information on these methods.

Copyright for ISOGRIDS is with IAEA and the Laboratory of Atmospheric Physics, University of Patras. Users are kindly requested to cite this software as "ISOGRIDS – ISOtopic GRIdded Rainfall Data Software. Available at (retrieved YYYY-MM-DD)". Please be aware that – as with all free software – only limited support can be provided, although it is planned to establish an FAQ site.
