Please contact the IS for details nearer the time of shipping. The user is responsible for coving the travel and subsistence expenses of the Facility Scientist while attending the instrument. The user is liable for all costs arising from the shipping of the instrument both to and from deployment.AMOF is not liable for any damage or injury arising from the deployment or operation of this instrument when unattended by the Facility Scientist.The user is responsible for the instrument from the time it leaves the AMoF to the time it is returned and signed off as in an acceptable operating condition by the IS: this will be done as soon as is possible on its return.
Even so, the end-user must respect the fact that the system is a precision optical instrument that must be treated with great care.The system has been designed to be rugged and autonomous.This system must be insured by the user for £30K and covers loss, theft or damage to the instrument: damage is that over and above general wear and tear.Tubing to connect the 3321 APS to a sampling system or environment will not be provided Costs Particles with more than two crests, indicative of coincidence, are also binned separately but are not used to build aerodynamic-size or light-scattering distributions. In uncorrelated mode, these particles are displayed in the smallest size channel (less than 0.523 micrometers). The smallest particles may have only one detectable crest and are binned separately. The amplitude of the signal is logged for light-scattering intensity. Peak-to-peak time-of-flight is measured with a 4-nanosecond resolution for aerodynamic sizing. The use of two partially overlapping laser beams results in each particle generating a single two-crested signal. The configuration of the detection area improves particle detection and minimizes Mie-scattering oscillations in the light-scattering-intensity measurements. The APD then converts the light pulses into electrical pulses. An elliptical mirror, placed at 90 degrees to the laser beam axis, collects the light and focuses it onto an avalanche photodetector (APD). Light is scattered as each particle crosses through the overlapping beams. As particles exit the nozzle, they cross through two partially overlapping laser beams in the detection area. The aerodynamic size of a particle determines its rate of acceleration, with larger particles accelerating more slowly due to increased inertia. The APS accelerates the aerosol sample flow through an accelerating orifice.
