Relationships between TPM Delivery and Potassium Citrate Added

TPM deliveries of cigarettes with different amount of potassium citrate added were tested.The results showed that TPM deliveries of cigarettes treated were decreased to a minimum with increase of potassium citrate added within the range of mass percentage of 2.03%-3.12%. Although the amount of potassium citrate added for a minimum TPM delivery was related to original K content of cigarettes, it wasn't only determined by the original K content.
