Information: Finally - a pressurized automatedliquid sampler(PALS)for the fields of hydraulic oil contamination monitoring andpharmaceuticalparticle size analysis for viscous and volatile fluids. This batchsamplerhas such unique features as: a self sealing sample chamber,programmablevolumetric settings from 0.1 to 100 ml per cycle, automatic flushcycle,computer controlled and monitored sample chamber pressure andcorrespondingfluid flow rate. Couple this with state of the art counting/sizingelectronicsand a host of wide dynamic range sensors and you have a system that ishard to beat. The heart of the system is the AccuSizer 580 highresolutionpulse height analyzer that can count and size particles one at a time.Its DSP based architecture allows for user settable software channelsthatcan accommodate 2-32 tabular channel thresholds with correspondingparticlecount levels for determining pass/fail criteria of hydraulic fluids orpharmaceutical injectable drugs. A single click of the mouse convertsthe32 channel data to 128 logarithmically spaced channels for highresolutionparticle size determination. There is also a modular family of sensors covering thesize range from 0.5 to 2500 microns. These sensors are based on thetimeproven method of light extinction. Each sensor provides the dynamicrangeand solvent compatibility for even the most demanding applications. Thefluidics package combines computer controlled automation with aflexibledesign that can be configured in the field. Unique features include:selfsealing sample chamber that provides a targeted placement of samplecontainer,allowing for one handed insertion of sample bottle; continuousmonitoringof air pressure and sample fluid flow with greater than 0.1 mL fluidvolumesensitivity and control; quick disconnect user interchangeable criticalorifices for use with volatile fluids; enclosed air exhaust portallowingfor safe venting of chamber air; provision for pressurized air frommultiplesources including air tanks, house air, compressor etc...; inlinefiltrationand dehumidification provided for external air sources; computercontrolledflow providing greater accuracy for small volume injectable analysis(SVI's);shielded clear sample chamber with a unique design that places minimalaxial force on the glass sample chamber; multiple position sample feedtube allowing for non centered and adjustable elevation sampling. Userdefined tare/dead volume allows for intra- and pre- analysis flow,ensuringaccurate particle sizing. Now a complete analysis run can be accomplished witha single click of a mouse. Just place the sample container on thetargetpad and click on the run button. The stage will automatically: seal,lock,pull a vacuum in multiple stages to degas the sample (optional),re-pressurizeto the proper level to produce a flow rate of the liquid as defined bythe sensor calibration, sample a volume as defined by the pre analysisdead volume (optional), and measure single or multiple aliquots of thesample, display the results in one of the many predefined formats, savethe raw data in over 512 differential channels, drain the system, liftthe stage allowing removal of the sample bottle and produce a reportwithboth graphical and tabular data that includes pass/fail criteria asdefinedby any standard that the user would like to include as part of theconfigurationfile. All that the user has to do is place the next sample on thetargetpad and click on Run. Nothing could be easier! The software is a Windows based controller that notonlyprovides true multi-tasking capabilities, saving time and money, butalsooffers the unique features found on most leading edge Windows programsincluding: copy and paste features, allowing users to import tables andgraphs into other Windows documents for custom report generation,multi-leveloperational control with password protection, user definable criteriatablesfor embedding contamination standards into the software program. Thesystemprovides pass/fail alarms, multi-level data archiving, real time datatransferto popular database and spreadsheet Windows programs and unlimited userdefined customizable report templates. The PALS system is designedusinga modular approach and has provisions for automated (robotic) sampleintroductionand at-line process monitoring.
