Description
Malvern Panalytical Spraytec Particle Size Analyzer Repair
The Spraytec measures spray and droplet size distributions by laser diffraction in real time, across 0.1 to 2000 microns without changing optics, and at acquisition rates up to 10,000 measurements per second. That speed is the point: it resolves how droplet size changes through the life of a spray event, which is what inhaler, nasal spray and agricultural nozzle development depends on. An instrument sampling that fast is unforgiving of contaminated optics.
June Company’s certified technicians repair the Spraytec for inhaler and nasal spray developers, pharmaceutical formulation teams, agricultural nozzle manufacturers and automotive injection engineers. We diagnose and repair at the board and component level, and every instrument is functionally verified before it ships back.
Common Spraytec problems we fix
- Detector array faults — dead or noisy elements across the array, which distort the size distribution rather than stopping measurement.
- Laser output faults — intensity dropping, which reduces signal across the whole range.
- Optical contamination — spray residue on lenses and windows, which is the single most common fault on this instrument.
- Alignment faults — the optical bench out of alignment, so background and size results shift.
- High-speed acquisition faults — the electronics failing to sustain the full 10,000 measurements per second, losing transient detail.
- Background measurement faults — backgrounds not taking cleanly, which invalidates everything measured after them.
- Communication and software faults — the host software not connecting, or data not recording.
- Trigger and synchronization faults — acquisition not triggering with the spray event, which misses the part being studied.
- Purge and environmental faults — the optical purge failing, letting spray reach the optics faster.
- Power supply faults — instability showing as intermittent, hard-to-reproduce results.
FAQs
Backgrounds will not take cleanly. Is that the instrument? Usually optical contamination rather than a failure. It is the most common thing we find and the least expensive to put right, but left alone it will ruin a study.
Can you verify performance after service? Yes. We verify against reference standards and check that high-speed acquisition holds its rate, which a static test would not reveal.
Do you handle other Malvern particle sizers? Yes, including the Mastersizer and Zetasizer ranges.
