![]() The dispersion nozzle geometry is designed so that the air is accelerated to supersonic velocity (this is the Jet in PowderJet). There, the sample flows through a venturi nozzle where any agglomerates are dispersed using 360° compressed air and no impaction surfaces which may cause milling. Sample flows along the vibratory feeder before falling into the dispersion chamber. The two figures below show details of the PowderJet dispersion system and measurement cell. This fourth-generation of the PowderJet technology has built upon user feedback and previous versions to become the easiest to use, most powerful dry dispersion accessory available. To accomplish this, HORIBA created several tools such as a feedback control loop, scan filters, and more. The LA-960V2 PowderJet was designed from the very beginning with the goal of maximizing precision. Thus the PowderJet became just as important to the development team as the choice of laser, detector layout, and circuit design. Repeatability: Consistent control of aspiration settings deliver excellent sample-to-sample and instrument-to-instrument repeatability.When the LA-960V2 project was launched it had the explicit goal of producing not just the most advanced optical system but also sample handlers to take advantage of it.Rapid Measurements: Measurement time is usually 10 - 40 seconds, depending on the properties of the material.All data is saved on the system PC or can be exported to user networks. Simply place the sample in the tray and press RUN. Automatic sampling: The Microtrac MRB FLEX software facilitates the automation of measurement cycles.If required, multiple trays can be processed and combined into one measurement record. Large sample volumes: The removable tray can hold larger quantities of powder.This is ideal for applications where the material is expensive or produced in small volumes. Small sample volumes: Volumes can be as small 0.1 cm3.Dispersion conditions can be fine-tuned for measurement of even the most fragile materials. Flexibility: Compressed air and flow condition settings up to 50 psi (345 kPa) allow the operator to achieve optimal dispersion, even for highly agglomerated materials.A moving sample tray introduces the powder into the measurement system. The TURBOSYNC delivers a properly dispersed sample to the measuring cell of the analyzer, allowing for consistent and repeatable analyses. This eliminates cross contamination between different materials. Self-Cleaning: The wash feature ensures that the walls of the sample vessel are thoroughly cleaned during the rinse cycle.In addition to water and alcohol, this includes organic solvents like hexane or toluene. Resistiveness: The FLOWSYNC can be operated with a wide variety of carrier fluids.Auto-Dispersion: The FLOWSYNC’s fluid dynamics feature a built-in turbulence to ensure that all particles are moving constantly within the system, negating the need for an external stirrer.The recirculator fills, de-aerates and dilutes automatically. Connectivity: An integrated fill pump allows the user to connect any water or solvent source.Versatility: Users can program, save and recall unlimited SOP routines for fill, disperse, measure, rinse and run commands.Consistency: An in-line ultrasonic probe with variable power disperses agglomerated materials to ensure consistent sample dispersion during measurements.The FLOWSYNC’s automated filling, de-aerating, pre-circulating and circulating operation means that each sample is handled with a consistency that improves the repeatability of particle size distribution and imaging data. The patented BLEND routine allows users to examine materials over a wide range of sizes from 0.01 microns to 4000 microns. ![]() The powerful analyzer software provides both particle size distribution information as well as a multitude of morphological particle parameters. It also provides valuable information to researchers as they develop new materials and processes. The SYNC laser diffraction particle size analyzer is ideally suited for routine QC applications. The patented synchronous measurement technology allows users to make both a laser diffraction measurement and an image analysis measurement on a single sample, in the same sample cell at the same time With the SYNC particle analyzer, Microtrac MRB integrates its highly accurate tri-laser diffraction analyzer technology with its versatile dynamic image analysis capability to provide particle characterization practitioners with a unique measuring experience. ![]()
