Technical Program

The Technical Program is organized into keynotes, breakout sessions, a plenary session, and luncheon presentations. Each NEMC technical session consists of 4 – 8 oral presentations. The TNI sessions are primarily meetings of TNI committees and special sessions on laboratory quality, assessor issues, and updates on TNI activities.

All NEMC sessions and TNI meetings are open to all attendees according to your registration. Attendees have the ability to view presentations in-person or view a recorded version that will be made available shortly after the symposium. Registration is by full conference, which includes all events, or daily.

The Forum on Environmental Accreditation

The Forum on Environmental Accreditation (the Forum) held concurrently with NEMC, is the principal conference for addressing policy and technical issues affecting the accreditation of environmental laboratories in addition to field sampling and measurement organizations. The Forum features open public meetings of all TNI committees to allow quality professionals, chemists, analysts, microbiologists, engineers, and managers from federal and state agencies; commercial, municipal, state and federal laboratories; and many others who are actively involved and interested in laboratory accreditation issues to review what has been done and participate in the efforts to establish a national program for environmental laboratories and field sampling and measurement organizations. Details for the Forum meetings can be found at www.nelac-institute.org.

Mei Beth Shepherd, Information Technology Chair

Problem Statement: TNI’s Laboratory Accreditation Management Systems (LAMS), used to document the accreditation status of laboratories, contains 3500 “Analyte Codes” and 5000 “Method Codes.” These Codes are used by laboratories to report proficiency test (PT) results. For any particular test method, there may be many codes reflecting slight variations of the method. For example, there are 121 method codes for Standard Methods 9221. When laboratories report their PT results they must pick one of these as the method used. However, NELAP Accreditation Bodies may have selected a different code and thus will score the result as unacceptable.

9:00 am - 12:00 pmOptional Training Course: Understanding Microbiology Training Series, Part 1: Introduction to Microbiological Testing

Session Chair(s): Cody Danielson, Oklahoma DEQ
You must be registered for this course in order to attend.

This series will focus on microbiological testing of environmental samples. The series will not train to the TNI Standard, but rather will cover basic and advanced microbiological principals and how to implement requirements of Volume 1 Module 5 of the 2016 TNI Standard. The courses in this series will cover an (1) introduction to microbiological testing as well as testing techniques, (2) quality control, equipment/instrumentation verification, and media reagent preparation, and (3) in-depth information on microbiological methods and technologies. Analysts and assessors seeking to expand their knowledge beyond the Standard can do so by learning in-depth information on microbiological testing.

Part 1: Introduction to Microbiological Testing

This first course will provide participants with a general understanding of microbiological testing, techniques, method scopes and limitations, QC and technologies.

Topics addressed will include:
  • Microbiological Analytes
  • Microbiological Sample Integrity
  • Microbiological Lingo
  • Microbiological Positive And Negative Controls
  • Basic Microbiological Techniques Such As Serial Dilutions, Sterilization and Aseptic Technique
  • Microbiological Test Methods Across Multiple Programs

Agilent Technologies Recent Advances in Agilent GC/MS Technology
Contaminants in water and soil are a worldwide concern. Having rapid methods for identifying and quantitating volatile and semi-volatiles contaminants at low μg/L levels is a useful tool for protecting both human populations and wildlife. For environmental labs testing these water and soil samples, performance, efficiency and sustainability are key factors to viability. Recent advancements in Agilent GC/MS technologies deliver improvements in each of these areas. Of specific interest due to recent helium shortages, we will review a novel technology development to overcome challenges of using hydrogen carrier gas for GC/MS.

AGS Scientific, Inc. Model RA-7 Series Mercury Analyzer
The new Model RA-7 Series Mercury Analyzer from Nippon Instruments Corporation (NIC), which will be officially released in September 2022, introduces multiple enhancements and time-saving techniques for mercury analysis in wastewaters, soils, sediments & more by EPA Methods 245.1, 245.5, 7470A & 7471B. In addition to the RA-7’s discrete, direct purge design, additional technological advancements include the ability to combine up to three autosampler modules per each RA-7 detector with smart, time management software to maximum total sample throughput. These three autosamplers can be any combination of the three available configurations: standard (for pre-digested solutions), automated digestion for wastewaters, and automated digestion for soils & sediments.

Biotage LLC ISOLUTE® Phase Separators
Extract drying and concentration is a common procedure in environmental laboratories performing organic sample preparation. ISOLUTE® Phase Separators have been designed to rapidly separate chlorinated solvents from aqueous phases, under gravity. This functionality allows laboratories to seamlessly integrate the technology into their workflows without the need for additional vacuum or pressure manifolds. In addition, transfer steps can be eliminated with direct to concentration vial drying when utilized with TurboVap® concentrators.

Camsco OMNI-2200 Autonomous Real-time VOC Monitor
Comparison of real-time benzene measurements to PST (passive sampling tube, EPA Method 325) in Oil & Gas refineries and petrochemical sites is of great interest to the fenceline monitoring industry and the US EPA. The advantage of realtime measurements is that operators and Environmental Health & Safety supervisors can take action in real-time to mitigate emission events.

Shimadzu Scientific Instruments Magnifying Plastics Analysis
Plastic pollution, in the form of nano-, micro- or macroplastics, is going to persist in the environment for decades despite increasing efforts for developing new materials that degrade at a faster rate. Then, Where Do We Go from Here? As environmental analytical chemist, we can contribute to mitigate plastic pollution by enhancing the quantification and characterization of plastic materials and related contaminants. To support this effort, Shimadzu is introducing a new dual molecular spectroscopy technology-based system, never built into a single instrument, that will magnify your workflows for plastic analysis.

Dan Hickman, LAMS Administrator
Paul Junio, CSDP Executive Committee Chair
Mei Beth Shepherd, Information Technology Chair

Problem Statement: TNI’s Laboratory Accreditation Management Systems (LAMS), used to document the accreditation status of laboratories, contains 3500 “Analyte Codes” and 5000 “Method Codes.” These Codes are used by laboratories to report proficiency test (PT) results. For any particular test method, there may be many codes reflecting slight variations of the method. For example, there are 121 method codes for Standard Methods 9221. When laboratories report their PT results they must pick one of these as the method used. However, NELAP Accreditation Bodies may have selected a different code and thus will score the result as unacceptable.
