Particle Counters & Particle Analysis Systems
Particle counters and particle analysis systems measure the number and size distribution of particles in air, liquids or powders, which is central to cleanroom monitoring, injectable manufacture and materials work. This category covers airborne particle counters, liquid particle counters and particle size analyzers using techniques such as laser diffraction and dynamic light scattering. Buyers can compare new and used particle counters across portable and benchtop formats, confirm size range and flow rate, and contact sellers directly about calibration and sensor condition. Financing on qualifying listings supports larger cleanroom monitoring purchases.

Particle Counter & Analyzer Types
Instruments differ by the medium they sample and the size range they resolve. The variants below cover the main categories labs deploy.
Airborne particle counters
Instruments that count and size particles in air to classify and monitor cleanrooms against standards. Portable and remote versions cover spot checks and continuous monitoring.
Liquid particle counters
Counters that detect particulate contamination in water, solvents and injectable products. They are essential for controlling particulates in pharmaceutical and semiconductor fluids.
Laser diffraction analyzers
Systems that measure particle size distribution across a wide range using scattered laser light. They suit powders, suspensions and emulsions in QC and development.
Dynamic light scattering systems
Instruments that size sub-micron and nanoparticles by analyzing scattered light fluctuations. They are widely used for proteins, colloids and nanomaterials.

Why Choose Machinery Masters
Verified Sellers Only
Every seller is verified before a single listing goes live. Machinery Masters also reviews listings for accuracy, so buyers can commit to high value machinery with confidence.
Global Reach
Listings come from sellers across Europe, North America, and beyond. That reach widens the options past any regional dealer network, and it is often the only way to find discontinued models in good condition.
Flexible Financing Options
Qualifying listings carry financing through partner providers. Terms are shown directly on eligible product pages, spreading the cost instead of draining working capital in one hit.
Direct Seller Contact
No broker sits between the buyer and the seller. Ask about service history, arrange inspections, and negotiate directly with the person who actually knows the machine.
Applications and Uses
Particle measurement supports both contamination control and materials characterisation. The settings below show where it is applied.
Cleanroom classification and monitoring
Facilities count airborne particles to classify cleanrooms and confirm ongoing compliance. Continuous monitoring protects sterile and controlled manufacturing environments.
Injectable and parenteral QC
Pharmaceutical labs check liquids for particulate contamination to meet strict injectable standards. Liquid counters provide the sensitivity these limits require.
Powder and formulation development
Developers measure size distribution to control dissolution, flow and product consistency. Laser diffraction guides formulation decisions across many industries.
Nanoparticle and colloid research
Researchers size nanoparticles and characterise stability in suspensions and emulsions. Dynamic light scattering resolves the sub-micron range these studies target.
Benefits from Machinery Masters
As a branch of Analytical Instruments & Detection Systems, this category gathers particle counters and particle analysis systems and connects you with sellers who confirm calibration and sensor status.
Air, liquid and sizing instruments together
Particle counters for every medium and the analyzers that size them share one category, so you match the instrument to your contamination or sizing task. That is harder across separate specialist suppliers.
Extend monitoring without full new-instrument outlay
A well-kept used particle counter lets you add a monitoring point or lab capability affordably. That makes broader contamination control practical for more facilities.
Size range and calibration checked with the owner
You confirm size range, flow rate and last calibration directly with the seller. For regulated monitoring, those details decide whether the counter fits your programme.
Frequently Asked Questions About Particle Counters & Particle Analysis Systems
Match the instrument's smallest detectable particle size and sample flow rate to your standard or method. Cleanroom classification specifies particular sizes and sample volumes that the counter must meet. Confirm these figures with the seller against your requirement. Choosing the wrong range leaves the instrument unable to support your monitoring.
Calibration is central to particle counting, so ask when the instrument was last calibrated and by whom. Regulated monitoring usually requires periodic recalibration to a recognised standard. Factor a fresh calibration into your commissioning plan if records are older. Confirmed calibration status tells you how ready the instrument is for use.
The optical sensor is the heart of a particle counter and its condition affects accuracy. Ask about run history, any pump or flow issues and whether the sensor has been serviced. For liquid counters, confirm the flow cell is clean and undamaged. Sensor health matters more than external appearance.
Confirm the counter reports the particle sizes and volumes your classification standard specifies. Ask whether the software generates the reports your programme needs. Some instruments include sample locations and recipe management useful for routine monitoring. Matching capability to your standard keeps compliance straightforward.
Sellers are identified on the marketplace, so you can request model details, photographs and calibration records directly. Ask whether the instrument was removed in working order and why it was decommissioned. Dealing with the owner means your technical questions reach the right person. That openness supports a sound purchase.
