Particles size analyses by Malvern Mastersizer 2000 apparatus (crystals, particles, pellets, drops ect.)

Application:

The Malvern Mastersizer 2000 is the major apparatus for a range of applications involving suspensions, emulsions systems and dry powders. Half-automated and manual dispersion units can be used for wett- and dry measurements. Sample content is 18-1000 ml or 0,5 - 25 g powder. The entire 0.02-2000µm measurement range is accessed using a single-lens system. 

Specifications:

Within the Mastersizer 2000 system, consistent and controlled measurements are achieved through the clear specification of sample dispersion units and critical operating parameters within SOPs. With the automatic application of full Mie theory, the appropriate optical model is used whatever the size range being measured. This ensures method development and definition to ISO13320-1 guidelines.

• ISO9001-2000
  
• ISO14001
  

The performance of the Mastersizer 2000 optical bench can be verified using standard latices following Malvern’s well-established IQ/OQ procedures.

Measurement:

• Individual sample preparation (dry/wett measurement)
  
• To find the suitable dispersant media (water, organic solvent, oil, air)
  
• Determination of the useful computer program
  
• sonication (opcional)
  
• size analyses by 9 paralel measurements with 3 qualified reports
  
• Calculation with Mie theory, graph about distribution
  
• CD containing all of the results (opcional)
  

Working time: min. 1,5 h/sample
