Brooks Instrument has introduced a family of direct liquid injection (DLI) vaporisers for liquid-to-vapour applications.
Each DLI vaporiser is customisable for every customer's application requirements and overcomes the operational limitations of conventional vaporising technologies, such as bubblers or vapour draw systems, and flash vaporisers, Brooks said.
A Brooks DLI vaporiser employs heated gas, rather than a hot metal surface, to accomplish liquid vaporisation.
As liquid enters the heated gas chamber, it is atomised by a carrier gas stream.
Once the atomised liquid contacts the hot gas, it immediately changes to vapour.
The result is chemically pure vapour, free of decomposition by-products or liquid carry-over.
Moreover, a Brooks DLI vaporiser can accept multiple liquid inlets and will generate perfectly mixed vapours.
Brooks offers vaporiser designs to accommodate a range of liquid properties: extremely low vapour pressures (sub-1 torr), very low flow rates (sub-5 grams per hour), and very high flow rates (more than 15 kg/hr).
Brooks DLI vaporisers are efficient at producing vapour from liquid.
Every Brooks DLI vaporiser system can be delivered as a fully integrated system or as individual components.
