COPLEY SCIENTIFIC – A BRIEF HISTORY Copley Scientific was founded by Frank Copley in 1946 to manufacture and supply laboratory equipment and glassware to the pharmaceutical industry.The company has been based in Nottingham, UK, since that date. Today, users of our instrumentation demand that it is (a) precise and accurate (b) simple to use and operate and (c) robust and rugged. In 1957, Copley Scientific began to focus on test equipment for pharmaceutical solid dosage forms. As a result we have built up a wealth of experience in supplying and supporting such equipment in both the UK and internationally....

AIR SAMPLING AND PARTICLE ANALYSIS PARTICULATE MATTER (AEROSOLS) AIR SAMPLING AND PARTICLE ANALYSIS Particulate Matter (PM), alternatively referred to as Aerosols, Fine Particles or Particulates, comprises small particles of chemically and physically diverse solid or liquid suspended in a gas. In the case of ambient air, this Particulate Matter is a complex mixture of solid and liquid particles many of which, such as bacteria, dust, pollen, smoke, spores and soot, can be hazardous to health. More specific particulate matter generated by industrial and construction processes can be equally, if...

Wide Range Particle Sizing INTRODUCTION The miniaturised Wide-Range Particle Spectrometer Model 1000XP (WPS) is a must-have instrument for the aerosol and environmental research laboratory. It is the only general purpose high-resolution spectrometer available on the market that combines laser light scattering, differential mobility analysis and condensation particle counting in a single instrument to measure the diameter and number concentration of aerosol particles in a sampled air stream. The differential mobility analyser (DMA) and the condensation particle counter (CPC) can measure aerosol...

WIDE RANGE PARTICLE SIZING WIDE-RANGE PARTICLE SPECTROMETER MODEL 1000XP (WPS) The three instrument components (LPS, DMS and SMS) can be used singly or in combination in one of five operating modes: Particle size distribution in the 5 nm –10 micron range is a critical parameter in the characterisation of an aerosol cloud and is a vital area in environmental air monitoring and laboratory research. Hitherto, the conventional approach to particle sizing has been a somewhat haphazard collection of laser particle counting, differential mobility analysing and condensation particle counting equipment...

WIDE RANGE PARTICLE SIZING WIDE-RANGE PARTICLE SPECTROMETER MODEL 1000XP (WPS) PRINCIPLE OF OPERATION The schematic on the previous page shows the standard WPS Model 1000XP configuration. The Laser Particle Spectrometer (LPS) is a single-particle, wideangle optical sensor used for measuring particle size from 350 nm to 10 microns. Particles are drawn from the aerosol inlet at a flow rate of 0.70 L/min and focused with a 4.5 L/min flow of sheath air towards the centre of a ribbon-shaped laser beam generated by a laser diode (780 nm, 5 mW). Light scattered by each particle is collected by a spherical...

WIDE RANGE PARTICLE SIZING WIDE-RANGE PARTICLE SPECTROMETER MODEL 1000XP (WPS) The DMA voltage can be either stepped (Differential Mobility Spectrometer or DMS Mode) or scanned exponentially (Scanning Mobility Spectrometer or SMS Mode). The cylindrical DMA works in a re-circulating mode whereby the sheath air flow is in a closed loop with a steady flow of 4.5 L/min accurately maintained by a feedback control system to improve size response and resolution. At the same time, sensors monitor the absolute pressure and temperature of the air flow, the results of which are used to compensate for changes...
