Nerudia have recently installed a new e-cigarette testing instrument in our state-of-the-art analytical lab. The new equipment, which is a controlled activation and collection system for nicotine delivery devices, will enable us to assess e-cigarette devices and develop a universally accepted method of capturing their output. This will allow for accurate and reliable precise determination of analytes.
Our onsite innovations team have assisted this process by designing attachments, and printing them in 3D, which allow for seamless integration of the e-cigarette device and the analyte capture technology.
The parameters of the new instrument are customisable, and it can be calibrated to compensate for resistance of airflow provided by the device, as well as the analyte capture technology used. This gives a level playing field so that when the machine is set to draw 50ml, for example, this can be assessed and cross-validated against another model in a different laboratory, or the same equipment on a different day. This allows for accurate and repeatable results that can be relied upon. We are currently defining the true capabilities of the instrument for precision and accuracy, and results obtained so far are showing great promise.
Here at Nerudia, we are refining analyte capture technologies to determine the most appropriate process for the analyte at the level in question. This is then coupled with analytical methodology that has detection levels and precision fit for the intended use of the data. A worked example of this would be acetone determination. Methods exist that can determine sub part-per-billion levels of acetone, however if the expected output or the safe exposure levels are found to be within the part-per-million range then other more suitable methods can be better utilised. These methods may be less prone to environmental contamination and less susceptible to errors introduced in sample dilution and manipulation techniques, and therefore give more precise results. We will update on this work as it progresses.
