After Gravimetry (weight analysis) sample can be analyzed for particle size, nature (metallic/non-metallic/fibre) and their size classification. Depending upon minimum particle size and automation level required, there are different models.

Automatic (Motorized) Particle Analysis System

Model: DeXel-Filtrate ™ Optical

Fully Automated Analysis System Usually Consists of :

• Upright Optical Microscope with Motorized stage
• High resolution camera and
• DeXel – FilTrate Imaging software

A. Upright Optical Microscope with Motorized stage

Quick Overview :

• UIS System, Infinity plan Optics
• Wide magnification range from 40/50X to 1000X
• High resolution Planchromatic objective lenses 4X/5X, 10X, 20X, 40X, 100X( Dry) fitted on quadruple nosepiece
• Motorized Stage - Integrated mechanical stage size 150mm X 150mm or better; Range of motion 75 mm X 75 mm. Programmed movement by dedicated stage control software and also movement by arrow Keys on keyboard
• Motorized focusing through stage control software
• Bright Field Illumination by 6 volt, 20 watts Halogen bulbs with intensity control
• Polarizer and Analyzer facility
• Specially designed sample holders for different filter paper sizes

Microscope can be very effectively used for Metallography analysis as it has 40/50X to 1000X magnification range

B. High Resolution Camera

Quick Overview :

• Compact high resolution, 5 MP scientific grade
• Fast USB 2.0 connectivity to capture images at high and precise speed matched with programmed motorized stage
• Superior image quality to enable processing of micron size particles and separation into metallic, non-metallic

C. DeXel-FilTrate Imaging software

Quick Overview :

• Specially designed Imaging software for analysis of particulate contamination
• Analysis as per various international standards like ISO 4407, ISO 16232, ASTM F 312 etc and as per any other OE standard
• Seamless stitching of all the captured micro images to generate a single image of entire filter paper. This will join fibers and large particles broken in different frames (due to constraint of frame size) so as to analyze and deliver the results for their true sizes
• Separation of particles as Metallic, Non-metallic, fiber and Distribution of them as per their sizes
• Mean, Median, Standard Deviation etc statistical parameters
• Specially designed sample holders for different filter paper sizes
• Report generation as per customized format. Facility for multiple report formats as per multiple OE standards

Report includes

Total area scanned, Total No. of particles, separation as per type (metallic, non-metallic and fibre), distribution as per size, geometrical parameters such as major and minor axes, area, perimeter etc for individual particle, Largest Metallic, Non-metallic and fibre particle etc
