MEASUREMENT AND INSTRUMENTATION

	Aerosol Concentration The new Microdust Pro features an extended aerosol measurement range of 0-25,000 mg/m^3. This instrument can be coupled to any CH exposure system to provide total concentration of aerosol, or sampling via special adapter at a nose-only animal exposure port, recording the available concentration seen at the animal's nose. In addition, RS-232 as well as analog output capability enable this device to be used in several "closed-loop" feedback configurations to regulate aerosol concentration from generating devices, such as the Vilnius Dry Aerosol Generator
	MOUSE BREATH METABOLISM	The Mouse Breath Metabolism sampling device is a new offering from CH Technologies. By using a calibrated high-precision flowmeter, coupled with a special double-containment mouse holder system, expiratory components of a single mouse are captured in a coated mylar "Quintron" type breath collection bag. A system of valves enables repeatable sampling under different conditions or using various test specimens. Collected breath can then be transfered to various measurement instruments without loss for further analysis.
