The Scentroid SK5 EN13725 Odor Panelist Sensitivity Kit is designed to provide accurate N-butanol mixtures of 5 to 50 ppm from a liquid N-butanol source. The N-butanol mixture can then be used to screen and odor panelist using the Scentroid SM100 or any other Scentroid olfactometer in accordance with standard EN13725. The mixture is accurate and repeatable thanks to the fixed volume evaporation chamber, micro-litre syringe, and pre-purged Tedlar bag.
Every odour regulation requires the screening of the odor panelist using diluted N-butanol samples. Until now, the only available source of a diluted N-butanol sample was to purchase pre-mixed pressurized cylinders. The cylinders were cumbersome to transport, required a special permit and storage facility, and would only be accurate in dilution if shaken or rolled just before use. The Scentroid SK5 Sensitivity kit provides an easy and reliable solution for creating exact N-butanol samples that can be used for panellist screening. Liquid N-butanol is mixed with clean odourless air at a fixed ratio using a glass micro-syringe and a stainless steel evaporation chamber.
The N-butanol kit is easy to transport and store, does not have expiration issues, and allows variable concentration.
| N-Butanol (µL) | Concentration (ppm) | Dilution lower limit (20 ppb) | Dilution upper limit (80 ppb) | Plate | Range |
| 1 | 40 | 2000 | 500 | 2 | 2 to 7 |
| 0.75 | 30 | 1500 | 375 | 2 | 2 to 9 |
| 0.5 | 20 | 1000 | 250 | 2 | 4 to 12 |
| 0.25 | 10 | 500 | 125 | 3 | 1 to 5 |
| 0.1 | 4 | 200 | 50 | 3 | 3 to 10 |
