Article Synopsis
  • Accurate characterization of tobacco product emissions is crucial for evaluating their health impacts, and a leak-tight seal is necessary for reliable data collection.
  • A prototype universal smoking machine adaptor (USMA) was developed to work with various tobacco products, demonstrating effective sealing with different shapes and sizes.
  • Testing showed that emissions measured with the USMA were consistent and precise, often outperforming other adaptors in repeatability and accuracy.

Objective: We aimed to measure separately the contributions of heat and humidity to changes in levels of hemoglobins A and S in dried-blood-spot (DBS) samples.

Design And Methods: We stored paired sets of DBSs at 37°C for predetermined intervals in low-humidity and high-humidity environments. Hemoglobin A and S levels of all samples in each complete set were measured in a single high performance liquid chromatography run.
