tobaccoasia 55 product-specific solutions and its standard mod- els. "We believe that fast online measurements of specific analytical parameters are more and more in focus of interest. Therefore we have developed our LX-TOF-MS combination to directly quan- tify specific smoke components right when they emerge. But in other cases we have of course also developed application solutions together with our customers," said Schmidt. Besides its SEIVS B-01 Smoke Exposure In Vitro System for biological toxicity testing in a rotary setting, Burghart is additionally offering the MSB-01 Mimic Smoker and the S-GEN B-30 Smoke Generator. "Together with the SEIVS B-01, they're examples of smoking machines that we've developed for specialized tasks and differ- ent industry needs," said the company's managing director. Being among the surprisingly well represented German suppliers, all of Vitrocell's basic models can be supplemented with e-cigarette packages that take into account different holder require- ments and square puff profile capabilities. "Special holders required for various e-cigarette designs can be easily exchanged within seconds and we offer required software upgrades via our remote servicing tools," asserted Krebs. Vitrocell currently also is developing a new model, the VC10 S-Type, which is expected to be introduced in the fourth quarter of 2014. "It's [go- ing to be] a ten-port smoking machine for medium and high throughput with special features that are important for both combustion as well as elec- tronic cigarettes, such as a universal holder sys- tem, automated puff actuation of e-cigarette types that are button-actuated, and special temperature conditioning of the some path," hinted Krebs. Another one of the company's purpose-designed models, the VC10 ChemControl, provides the possibility for puff-by-puff smoke analysis. Besides its already mentioned standard mod- els, Cerulean also supplies machines for sidestream smoke capture and analysis, as well as specialized units for cigar, NO/NOx, LIP, and freeburn testing. Standard models not recommended for e-cigarettes While the general consensus among most manu- facturers seems to be that no marginally different equipment is needed for e-cigarette testing and that basic smoking machine models can be deployed either after minor adjustments or even without any modifications, Cerulean does not recommend the practice. "Although our standard models can be used for e-cigarettes, we have designed and recently launched the CETI8, a dedicated device for this purpose, and with a dramatically reduced footprint and lower price," said Paul Glenn. In his opinion, "using a dedicated machine is important to ensure there is no cross contamination between conventional cigarettes and e-cigarettes." Borgwaldt likewise cautions against standard machines in e-cigarette testing. "The design variety of e-cigarettes and vaporizers is very wide, which consequently demands for specific technical ad- justments in the aerosol generator," explained Schmidt. "Beside the danger of contamination, which will falsify the analysis results, you have to consider the strain on the generator's mechani- cal parts. Puff volume, frequency and particularly puff numbers require special attention [with e- cigarettes]." Furthermore, aerosol sensors for end point determination and mechanical activation systems must be purpose-designed to ensure con- trolled operation, and thus, reliable results. "For these reasons alone, we do not recommend the use of a standard smoking machine in e-cigarette testing," Schmidt concluded. Borgwaldt's Thomas Schmidt Cerulean's Paul Glenn Borgwaldt LX20
