Chemists and chemical engineers can now use a higher accuracy alternative to mechanical syringes - InterTech Development Company’s MicroPulse - a solid state means of producing small, short pulses of various gases. The compact (145x52x35mm) MicroPulse contains a miniature heat exchanger and precision temperature control that can be fitted into process control circuits without adding volume.

InterTech’s MicroPulse can deliver gases up to 1.75scc/m at STP. The required flow during the pulse period is automatically controlled via an 8-bit digital interface by a PLC or other external controller. The user can pre-set flow direction (inward or outward), volume-flow (cc/minute) or mass-flow (standard cc/minute) pulses over a wide pressure range.

The multiple advantages of InterTech MicroPulse technology include:

• There are no moving parts or pneumatic valves to stick or wear.
• There are no small gaps or orifices to get clogged.
• No compressed-air source is required.
• Application can initiate a flow pulse automatically, at any interval.
• Multiple different flow values can be produced as required by application.

Engineering analyses of testing application requirements and expected savings at specified gage R&R using InterTech patented test technology and customized software are available at no charge.
