SKOKIE, Ill., Oct. 7, 2010 — Laser technology researchers can now use a higher accuracy alternative to mechanical syringes. InterTech Development Co.’s MicroPulse provides a solid-state means of producing small, short pulses of various gases. The nonmechanical syringe measures 145 × 52 × 35 mm and contains a miniature heat exchanger and precision temperature controller that can be fitted into process control circuits without adding volume. It delivers gases at up to 1.75 standard cubic centimeters per minute at standard temperature and pressure. The required flow during the pulse period is automatically controlled via an 8-bit digital interface by a programmable logic or other external controller. The user can pre-set flow direction inward or outward, volume-flow (cubic centimeters/min) or mass-flow (standard cubic centimeters/min) pulses over a wide pressure range. Overall accuracy and repeatability of 0.1% can be achieved over extended periods of fully automatic operation. There are no moving parts or pneumatic valves to stick or wear, and no small gaps or orifices to get clogged. No compressed-air source is required. An application can initiate a flow pulse automatically, at any interval, and multiple different flow values can be produced in quick succession, as required. Engineering analyses of testing application requirements and expected savings at specified gage repeatability and reproducibility using proprietary and patented test technology and customized software are available at no charge.
