Sample Preparation Workshop - Ottawa - November 16, 1st Announcement.

SPECTROSCOPY SOCIETY OF CANADA Notice of Workshop - Ottawa - November 16

Subject: Sample Preparation Workshop - Ottawa - November 16
Dear Colleagues, The Spectroscopy Society of Canada has arranged for a seminar on sample preparation for Tuesday, November 16, 2004. The seminar will be conducted by Dr. Joe Brenner of Ben Gurion University in Israel. He will be giving a modified version of his popular ACS course. Dr. Brenner is widely acknowledged as one of the World's leading experts on sample preparation with nearly 100 publications on the subject. Please see the attachment for more details or contact Conrad Gregoire at 613-995-4213 or Regards, Victor Benham.
Join the Spectroscopy Society of Canada on Tuesday, November 16, 2004, for a sample preparation workshop conducted by Dr. Joe (Isaac) Brenner. One of the world's leading authorities on sample preparation, Dr. Brenner will deliver a version of his regular ACS sample preparation course.
Sample solution integrity and reliability of preparation protocols dictate whether results are valid. Errors in sample preparation are the main source of uncertainty in the entire analytical process. This short course will address the status, requirements, and challenges of sample preparation for a wide range of analytical tasks and materials using ICP-AES and MS. The advantages and disadvantages of various procedures will be critically evaluated using conventional figures of merit such as LODs, contamination, multielement capability, recovery of labile and refractory elements, convenience of operation, automation, cost, sample size, and sample throughput. Among techniques discussed will be fusions, sinters, mixed acid routines in closed vessels and microwave ovens, and partial digestion for mode of analyte occurrence.
The uniqueness of this session is the impact of sample preparation on the measurement system - on interferences in the aerosol generation and transport systems, in the plasma and in the ICP-MS interface. Sample preparation therefore is not a stand-alone part of the analysis but critically effects sample introduction and detection. Several selected applications for analysis of environmental, geological, biological, metallurgical, petrochemical and energy-based materials such as fly ash and coal, crude oils and multiphase bituminous sludges will be described. In particular, routines employed in trace element analysis of environmental and waste materials (Standard Methods, EPA 200.7, 200.8, SW846 6010 and 6020 and the 3000 series) will be detailed. Aspects of laboratory accreditation will be highlighted.
Agenda: 8:00 AM Registration: Coffee and light refreshments will be served.
8:30 AM Decomposition Strategies: - Advantages of solution techniques, calibration and validation. - Strategies. Acid decomposition, fusions, sinters, open dish, pressurized containers, microwave digestion. - Partial decomposition and extraction for determining mode of occurrence of elements and species - Advantages and disadvantages of the strategies in terms of chemical resistance of refractory samples, loss of volatiles, poor recovery, reagent cost, contamination and sample throughput. - Instrumentation
10:30 AM Applications: Preparation of geological, environmental, biological and energy-based samples such as fly ash, coal, crude oil and multiphase bituminous sludge: - Open dish and closed containers, microwave dissolution and fusion procedures for selected materials be described in detail. - The procedures will be evaluated using conventional figures of merit such as limits of detection, recovery, sample throughput, and contamination. - Sample preparation for compliant analysis of waters, wastewaters, and solid wastes (EPA 200.7, 200.8, SW-846 6010B, 6020A and the 3000 series) will be highlighted. - Partial extractions using species selective reagents
Effect of sample preparation on the plasma and sample introduction systems: - Salt and acid interferences, memory effects. Easily ionized element effects, salt clogging in torch injectors and in ICP-MS cones.
12:00 PM Lunch: An opportunity to meet with other analysts and exchange views.
1:00 PM Applications (continued): - Compensation of interference effects: Review of approaches to overcoming sample-preparation related interference effects in ICP-AES and MS. - Low consumption nebulizers, robust ICPs, internal standards, and reaction and collision cells. - Axial vs. radial ICP-AES considerations
Discussion: - Comparison of open and closed vessels with microwave-assisted digestion. - Problem solving in sample preparation. - Is direct solids analysis using laser and spark ablation and slurry nebulization alternatives to sample preparation.
2:30 PM Finish.
