Webinar Date/Time: Thu, Feb 22, 2024 11:00 AM EST
Looking for ways to improve your environmental metals and organics analyses in aspects such as lab throughput, data quality, labor, costs, and safety? This eWorkshop uses a total workflow approach to sample preparation that promises to help you optimize your operations and offers practical advice for preventing workflow disruptions that negatively affect your lab’s performance.
A key part of the workflow for an environmental laboratory is sample preparation. Most sample preparation steps are manual, time-consuming, costly, error-prone, and have elements of risk associated with exposure to concentrated acids and solvents.
This eWorkshop presents a total workflow approach to sample preparation for organics and metals, including a special case for mercury. It examines ways to improve key measures of the process such as lab throughput, data quality, costs, and safety. Practical advice is provided for preventing workflow disruptions, such as lengthy and incomplete digestions and extractions, sample contamination, and complicated preparation steps for mercury, all of which can prevent a laboratory from meeting their overall performance, cost, quality, and safety goals.
Several of the presentations include demonstrations of the systems and methods being discussed, including acid purification, automated reagent addition, vessel handling, microwave digestion, microwave extraction, sample filtration, labware cleaning, and Direct Mercury Analysis, all reflecting approved EPA methodologies.

11:00 am eWorkshop Introduction, Spectroscopy
11:05 am Overview of a ‘Total Workflow’ Approach to Sample Prep and Why it Matters
Giulio Colnaghi, Milestone
This introduction to a ‘total workflow’ approach to sample preparation for metals and organics analyses examines not only the evolution of the pivotal microwave digestion and extraction processes, but also additional steps in the workflow that are critical to meeting lab performance requirements. By optimizing these steps, laboratories are better prepared to overcome the challenges they face and avoid workflow disruptions that impede the analysis process and result in higher costs and avoidable risks.
11:25 am The ultimate in environmental workflow simplicity: Direct Mercury Analysis:
Jesse Davidson, Milestone
Milestone’s Direct Mercury Analysis (DMA) approach eliminates the complex and error-prone sample preparation steps associated with classical cold vapor AAS as well as the hassles of analyzing samples for mercury via ICP-MS. This presentation demonstrates how the simple “load and go” DMA approach provides significant ROI, safety improvements, more consistent data quality, and automated processing of environmental samples in accordance with EPA SW-846 method 7473.
11:55 am Microwave extraction, solvent addition, and sample filtration for semi-volatile organics analysis
Jesse Davidson, Milestone
The Milestone Total Workflow approach for organics extractions provides an efficient, safe, and robust approach to soil extractions for target organic species such as PCBs, pesticides, and semi-volatiles. The key components of the workflow examined in this presentation include automated solvent addition, microwave extraction, and extract filtration. Advantages of the approach include faster preparations, lower costs, improved worker safety, and less impact on the environment.
12:25 pm Total Workflow Approach for metals -In-house acid purification
Eric Farrell, Milestone :
High-purity acid expenses for metals analysis can consume a significant portion of a lab’s operational budget. In addition, accidental contamination and supply chain challenges for obtaining high-purity acids can put a lab’s operations at risk. In this presentation you will learn the principles of sub-boiling distillation and how performing acid purification in-house can result in considerable cost savings, better quality acids, and ensure an uninterrupted analysis workflow.
12:40 pm Automated reagent dosing
Eric Farrell, Milestone
The reagent addition, or ‘dosing,’ step of the sample preparation process has traditionally been a tedious and laborious task within metals and extractions protocols, especially when it involves concentrated acids and organic solvents. This presentation shows how automating the reagent dosing process provides greater consistency, while removing the operator from exposure to harmful acid and solvent fumes and frees them to perform safer and more value-added tasks.
12:55 pm Microwave digestion, vessel handling, and sample filtration for metals analysis
Eric Farrell, Milestone
While still considered the 'workhorse' of many metals analysis laboratories, rotor-based microwave digestion systems can also be the weak link in a laboratory's sample prep workflow if something goes wrong. In this presentation you will learn how various aspects of rotor-based digestion systems, including the advantages of advanced vessel construction and simplified handling features, can work to optimize a workflow, as well as avoid disruptions such as the need to rerun samples due to incomplete digestions or cross-contamination.
01:30 pm Automated labware cleaning for metals labs
Eric Farrell, Milestone
Using acid baths and microwave systems for cleaning sample prep vessels and other types of labware can have a substantial impact on an elemental analysis lab’s throughput, workflow, and efficiency. In this presentation, you will learn how automating this step using acid-steam cleaning keeps your microwave system focused on digesting samples and removes the tedium and hazards of hand-cleaning labware from your staff.
1:45 pm Q&A
