Palm-sized Gas Chromatograph SYLPH
Palm-sized gas analyzer that can be used in a wide variety of fields
About Palm-sized Gas Chromatograph
A gas chromatograph is an analyzer for measuring the species and concentration of a mixed gas of multiple species.
We successfully developed a gas chromatograph with dimensions of 100 × 100 × 100 mm and a weight of around 1 kg for space applications through the JAXA Space Exploration Innovation Hub Center by utilizing ball SAW sensor technology.
Furthermore, we developed a portable palm-sized (A5 size) gas chromatograph called Sylph for terrestrial applications, and started providing prototypes. We received “JAXA COSMODE” usage licensing from JAXA.
The basic principle used in Sylph is that the sample gas is directly sucked in by a pump, and is condensed by a built-in compact condenser. The carrier gas is provided by a hydrogen canister filled with a hydrogen absorbing alloy, and the mixed gas is injected into the column by a high-speed heater in the condenser. The various gas components separated by the column are detected by the ball SAW sensor based on the different retention times.

- Carrier gas can be changed by a cylinder adapter (optional).
- For filling hydrogen to a canister, please prepare a hydrogen cylinder or a hydrogen generator at the customer.
- Long-term usage can cause binder components inside the canister to be detected. We recommend replacing it after about 1 year of use.
- Column types shown in the table below are available as standard products. If you would like to request a different type of co lumn, please contact us.
