Christopher Mitchell - Biotage
Evan Walters - Biotage
Deanna Bissonnette - Biotage

Environmental laboratories routinely follow the Environmental Protection Agency (EPA) 1600, 600, and 8000 series methods to analyze contaminants in surface water, groundwater, and wastewater. However, the physical and chemical complexity of these samples present significant challenges during sample preparation, including high particulate loads and matrix interferences. To address these challenges, many laboratories have adopted methods to reduce sample preparation volumes from the traditional 1L samples. While this approach minimizes handling difficulties, it can negatively impact laboratory reporting limits by increasing the detection limits for target analytes.   To overcome these limitations, we introduce a novel 47mm depth filtration disk holder incorporating the ISOLUTE® HM-N filtration product. This system effectively neutralizes high-matrix interferences and integrates seamlessly with solid-phase extraction (SPE) techniques. Laboratories can process 1L wastewater samples in under 10 minutes with unprecedented ease and yield a 35% reduction in solvent use. This innovative sample matrix filtration approach enhances performance criteria by reducing detection limits, increasing accuracy, and improving precision when compared to traditional liquid-liquid extraction and micro-extraction techniques. This work highlights the transformative potential of this new technology to simplify and optimize sample preparation workflows.  Environmental laboratories that implement the 47mm depth filtration disk holder for EPA 1600, 600, and 8000 series methods will maximize sample processing efficiency, improve sustainability, and produce reliable data.

Angelina Precilla - Koehler Instrument Company
Lei Andre Delos Reyes - Koehler Instrument Company
Zachary Slade - Koehler Instrument Company

Reliable performance of middle distillate fuels (jet and diesel) hinges on their ability to resist oxidative degradation under elevated temperatures. This study employs the Koehler Reflectance Colorimeter to quantify filterable insoluble formation in distillate samples according to ASTM D6468. Two 50 mL fuel aliquots are incubated at 150 °C for prescribed intervals (90 min and 180 min), then cooled to ambient temperature in darkness to allow particulate aggregation. A vacuum filtration system collects insoluble residues on pre-weighed filter pads, which are subsequently placed atop the photosensor for reflectance measurement. Calibration of the instrument is achieved using a black cavity standard (0 % reflectance) followed by a reference plaque with a known reflectance value. Reflectance values are averaged across duplicate samples to yield a reliable indicator of fuel stability: lower percent reflectance corresponds to higher insoluble content and diminished thermal stability. By automating calibration, data capture, and averaging protocols, the K30700 unit provides rapid, reproducible insights into fuel quality. This reflectance-based approach enables early detection of oxidative degradation, supporting safer storage, transport, and in-service use of critical distillate fuels.

Mojan Jafaripour - Koehler Instrument Company

The dropping point indicates the temperature at which a grease transitions from a semi-solid to a liquid state. This is an important parameter, since a grease that is fully liquid no longer possesses the same lubrication properties. This poster introduces enhancements to the traditional ASTM D2265 dropping point test. By incorporating a High Temperature Dropping Point Apparatus and by replacing the traditionally used mercury thermometers with thermocouples, we were able to create a safer and more accurate testing method. By modernizing the temperature sensing component, the new method not only maintains the same setup, heating rate, and sample requirements stipulated in ASTM D2265, it also greatly improves measurement precision, repeatability, and operator safety. Thermocouples allow for remote monitoring, which significantly lowers exposure risk to high-temperature equipment for an extended period of time. Thermocouples eliminate the use of mercury, a hazardous material linked to central nervous system, kidney, and liver damage. Thermocouples offer superior durability, longer service life, and reduced calibration needs. Furthermore, the redesigned setup eliminates the need for sample height alignment, significantly reducing errors that can be caused by the operator.
