Flow chart of VITROCELL® FTIR Heated Line, 180°C Hot Gas Mixer, 180°C Gasmet FTIR Analyser, 180°C Exhaust Controller Clean Air Heated Line, 180°C VITROCELL® FTIR On-line gas analysis of electronic cigarettes This setup was developed in close cooperation with Gasmet . The system offers a puff-by-puff quantitification of key constituents of aerosol from electronic cigarettes. It is combined with the proven VC 1, VC 1 S-TYPE, VC 10® and VC 10® S-TYPE smoking machines and offers a fast evaluation of the aerosol in intervals of 1 s. Therefore it is a powerful alternative to classical chemical analysis which takes time-consuming steps by trapping, extraction, measurement and evaluation. Sampling and measurement system configuration: 1 | Aerosol generated by VITROCELL® smoking machine ○ HCI, ISO or CRM 81 regimes ○ E-cigarette aerosol mixed with N2 carrier gas ○ Continuous purging after puff 2 | Controller for carrier gas (N2) ○ N2 flows from 50 ml/min up to 5.0 l/min ○ Integrated mass flow controller 3 | Hot Gas Mixer ○ Heated line after mixing of carrier gas and aerosol 4 | Gasmet FTIR analyser ○ Small volume sample cell, 200 cm path length ○ Calcmet PRO software & RS-422 for fast measurement (1 s measurement interval) Quantification of constituents of e-cigarettes Smoking Machines VC 1, VC 1 S-TYPE, VC 10® and VC 10® S-TYPE FTIR Analyser Controller 168
