Organomation blowdown evaporators are well known by those completing PFAS methods focused on drinking water, specifically EPA Method 533 and 537.1. While the N-EVAP tends to be most popular with academic researchers, environmental labs needing to concentrate large sample batches prefer the MULTIVAP evaporator.
EPA Method 1633 is a meticulous analytical procedure designed to identify and quantify per- and polyfluoroalkyl substances (PFAS) in various matrices, including solids, aqueous samples, and biological tissues. This method is essential for monitoring these persistent and potentially hazardous compounds in environmental and biological contexts.
While the method does not always mandate the use of evaporation, it offers flexibility for laboratories to integrate evaporation steps to optimize sample concentration. Organomation evaporators are particularly well-suited for this task, offering efficient and reliable sample preparation across different matrices. This article explores how Organomation evaporators, specifically the 24 Position MICROVAP, N-EVAP, and MULTIVAP, effectively concentrate samples for EPA Method 1633.

EPA Method 1633 covers three primary matrices:
1. Solids: Includes soil, sediment, and sludge.
2. Aqueous Samples: Comprising water samples from various sources.
3. Tissue: Pertains to biological tissues, typically from aquatic organisms.
For each matrix, specific sample preparation steps are crucial to isolate and concentrate PFAS compounds for accurate quantification.
While the method does not explicitly require evaporation for aqueous samples, laboratories may opt to modify the Solid Phase Extraction (SPE) procedure to incorporate evaporation. This is particularly useful when concentrating samples for more sensitive detection limits or when working with smaller volumes of methanol (less than 1 mL). For these applications, the 24 Position MICROVAP Evaporator is an ideal solution.
Key Features of the 24 Position MICROVAP:
1. Capacity: Can handle up to 24 samples simultaneously, enhancing throughput and efficiency.
2. Precision: Allows precise control of evaporation parameters, crucial for maintaining sample integrity.
3. Compact Design: Suitable for laboratories with limited space.
The MICROVAP ensures that the evaporation process is both efficient and consistent, providing concentrated samples that meet the stringent requirements of EPA Method 1633.
For solid and tissue samples, evaporation is a critical step in the concentration process. These procedures typically require the evaporation of approximately 20 mL of methanol.
Organomation's N-EVAP and MULTIVAP evaporators are particularly effective for this task. Depending on the configuration, these evaporators can efficiently remove 20 mL of methanol within 1-2 hours, making them ideal for high-throughput laboratory environments.
1. Efficiency: Capable of evaporating multiple samples simultaneously.
2. Adaptability: Can be configured to accommodate different sample sizes and types.
3. Precision: Offers precise control over evaporation conditions, ensuring uniform sample concentration.
