We have had a very positive response to the suggested LIMS training course tie-in with ASITA 2017. Tyler Coplen and Haiping Qi are prepared to teach a 2-day workshop on the installation and use of the LIMS software. This class is scheduled to take place PRIOR to ASITA 2017, specifically Friday June 23 / Saturday June 24, which will then flow into the ASITA 2017 conference ice-breaker Saturday evening.
Space is very limited and based on first come first serve basis - Limited to about 20 attendees.
NOTE: Though we currently have the required 20 attendees, we will be creating a waiting list. There is the possibility of adding another 2-day LIMS training course after ASITA 2017, if we get another 15-20 people interested. We will keep you posted.
Venue and morning / afternoon refreshments will be arranged though EIL at the University of Waterloo.
Please see the announcement below for details.
Title: Strategies to Improve Measurement Quality of Isotope-ratio Mass Spectrometers: A LIMS (Laboratory Information Management System) for Light Stable Isotopes Training Course.
Dates: June 23-24, 2017
Location: University of Waterloo, Waterloo Ontario, Canada in the Centre for Environmental & Information Technology (EIT) building.
Friday class 9:30am- 5:30pm EIT Rm 1009
Saturday class 9:00am – 5:30pm EIT Rm 2053
Cost: Free (Morning and Afternoon refreshments will be provided)
Lecturers: Tyler Coplen and Haiping Qi (U.S. Geological Survey, Reston, Virginia, USA).
For: Laboratories utilizing isotope-ratio mass spectrometers using ISODAT, MassLynx, Ionvantage, Analytical Precision, some Europa Scientific, and Micromass OS/2 v.1.67 CF files, some Sercon, and some Nu mass spectrometer files. Each Attendee will set up a laboratory database for their own stable isotope laboratory during this workshop. Among other things, attendees will learn how to (1) import files from mass spectrometers, (2) normalize data using isotopic reference materials interspersed among unknowns, (3) calculate mass fractions (concentrations) of carbon-, nitrogen, hydrogen-, and sulfur-bearing substances, (4) correct for change in isotope-delta value with amount of sample (so-called linearity adjustment), (5) adjust for isotope-delta variation over time of a run with variation in EA or TC/EA reactor performance, (6) create a sample submission Excel file for clients of the laboratory, (7) query all samples and results in the laboratory database using wildcards, etc., (8) track quality assurance over selected time interval, and (9) utilize USGS Excel sample files for EA and TC/EA sample preparation and analysis.
Some topics to be addressed during the workshop include:
1. LIMS for Light Stable Isotopes provides a convenient Windows environment to manage clients, projects, samples, and instrumental data. See https://isotopes.usgs.gov/research/topics/lims.html for additional details.
2. Isotopic data reporting guidelines within the framework of internationally distributed isotopic reference materials.
3. Although LIMS for Lasers 2015 is fully compatible with LIMS for Light Stable Isotopes, this proposed training class will not include discussion of LIMS for Lasers 2015 because training for this database application is regularly offered by the International Atomic Energy Agency in Vienna.
Software and Hardware Requirements: Attendees need a Windows (XP, 7 or 10) laptop with Microsoft Access and Excel 2007 to 2016 (32-bit only) with the latest service packs installed.
NOTE: The Windows OS can be 32-bit or 64-bit but Microsoft Office MUST be 32-bit only. AVOID 64-bit OFFICE.
Description of LIMS for Light Stable Isotopes:
The reliability and accuracy of isotopic data can be improved by utilizing database software to (i) store information about samples, (ii) store the results of mass spectrometric or laser-based isotope-ratio analyses of samples, (iii) calculate analytical results using standardized algorithms stored in a database, (iv) normalize stable isotopic data to international scales using isotopic reference materials, and (v) generate multi-sheet paper templates for convenient sample loading. Such a database program, the Laboratory Information Management System (LIMS) for Light Stable Isotopes, is used by a number of laboratories around the world. LIMS operates in a client-server mode and consists of a front end database containing code, forms, and reports, and a back end database containing the data of the laboratory (sample information, analysis results, sample submitters, etc). Major benefits of this system include (i) a dramatic improvement in quality assurance, (ii) an increase in laboratory efficiency, (iii) a reduction in workload due to the elimination or reduction of retyping of data by laboratory personnel, and (iv) a decrease in errors in data reported to sample submitters. Such a database provides a complete record of when and how often laboratory reference materials have been analyzed and provides a record of what correction factors have been used through time. It provides an audit trail for laboratories and serves as part of a laboratory's quality assurance program.
