Mastersizer 2000 Manual Fix
Velma Wiste
Two versions of the newunit are available, the Hydro MU (Plate 4) and the Hydro M, both of which aredesigned for manual preparation of wet samples. The higher specification Hydro2000MU has a built in ultrasonic probe with variable output and timer to ensureuniformity of sample preparation. However, as not all materials requireultrasonication to achieve dispersion, the Hydro 2000M without ultrasonicsprovides a highly cost-effective alternative.
The Hydro 2000M and MUboth use a 1000ml beaker as a sample tank. This is especially useful in areaswithout ready access to a water supply, and the relatively low cost of thisstandard laboratory item means that it can be easily replaced in the event ofsoiling or contamination.
Manual control is via anilluminated diaphragm touch panel designed for use under a wide variety ofoperating conditions. As part of the Mastersizer 2000 system, the Hydro 2000units are provided with a flow cell cassette that is automatically recognised bythe sizer software. This means that there is no need to pre-configure thesoftware and the unit can be used with the SOP (standard operating procedure)utility. Although the SOP software does not control the pump speed, as it doesin the system's automated sample dispersion units, it is possible to ensure thatdetailed operational instructions are displayed on the screen for users tofollow.
Operators guide including an overview, identifying the features, making measurements tutorial, viewing results, understanding views, handling measurement files, sample preparation and advanced features. The manual also includes a supervisor's guide, including administrator settings such as user setup.

Malvern Instruments Mastersizer 2000 Particle Size Analyzer and Hydro 2000MU
The Mastersizer 2000 particle size analyzer has set the standard for simple, straightforward operation. Modular in design, it has a wide range of automated sample dispersion units for the measurement of wet and dry samples. These are controlled through SOPs, providing ease of method development and transfer.
Broad particle size range suitable for many different applications.
Wide range of sample dispersion options for emulsions, suspensions and dry powders.
Fully automated simple SOP operation for ease of use and method transfer.
Full validation documentation available including compliance with 21 CFR Part 11.
Backed up by extensive applications knowledge across many different industries.
The Mastersizer 2000 uses the technique of laser diffraction to measure the size of particles. It does this by measuring the intensity of light scattered as a laser beam passes through a dispersed particulate sample. This data is then analyzed to calculate the size of the particles that created the scattering pattern.
A typical system is made up of three main elements:
Optical bench - A dispersed sample passes though the measurement area of the optical bench, where a laser beam illuminates the particles. A series of detectors then accurately measure the intensity of light scattered by the particles within the sample over a wide range of angles.
Sample dispersion units (accessories). Sample dispersion is controlled by a range of wet and dry dispersion units. These ensure the particles are delivered to the measurement area of the optical bench at the correct concentration and in a suitable, stable state of dispersion.
Instrument software. The Mastersizer 2000 software controls the system during the measurement process and analyzes the scattering data to calculate a particle size distribution.
This sale includes a Hydro 2000MU
The Hydro 2000MU is a large volume manual wet sample dispersion unit designed for use with standard laboratory beakers.
Designed to provide wet sample measurements for large sample volumes, the Hydro 2000MU provides:
600 - 1000ml sample volume using standard laboratory beakers.
"Dip-in" sample recirculation head for easy sample access.
Continuously variable pump and stirrer ensures bias-free sampling of dense materials.
Continuously variable sonication probe to aid agglomerate dispersion.
Manual keypad control of all measurement functions.
Software driven SOPs with appropriate user prompts to assist with adherence to GLP and ensure reproducibility of measurements.
Wet sample dispersion units use a liquid dispersant, aqueous or solvent based, to disperse the sample. In a wet dispersion, individual particles are suspended in a liquid dispersant. The wetting of the particle surfaces by the dispersant molecules lowers their surface energy, reducing the forces of attraction between touching particles. This allows them to be separated and go into suspension. In order to keep the sample suspended and homogenized it is recirculated continuously through the measurement zone.
For dispersants with high surface tension, such as water, the addition of a small amount of surfactant can significantly improve the wetting behavior and subsequent particle dispersion.
In order to disperse individual particles it is usual to apply some energy to the sample. Often this is through stirring or agitation, but for very fine materials or strongly bound agglomerates ultrasonic irradiation is sometimes used.

if you can contact us directly (help...@malvern.com) it may be better, otherwise try manual alignment, to see if the issue comes from the instrument which cannot align properly or if it is a laser power issue.
If you can't align manually, can you tell me if you can hear a "clic" while the background is being measured. If you cannot, it means the laser shutter does not work properly and needs to be readjusted (engineer visit required). If you can properly hear the "clic" but the power remains low it is a laser failure and in this case we would need to change the laser (engineer visit required as well).
Purchasing equipment capable of operating over a broad particle sizing range can be advantages to any organization. The Mastersizer 3000 features a smaller detector that allows to measure an upper size limit of 3.5 mm, although its optical bench size is much smaller than that of the Mastersizer 2000. Moreover, the way of making measurements at different wavelengths is optimized in the new system.
The selection of dispersions is based on the applications for which they are used. Dry dispersers such as Aero S or the Scirocco 2000 dispersers are required for some materials, while liquid dispersers such as the Hydro series of dispersion units are best suitable for other materials.
The Hydro LV offers similar functionalities to the Hydro 2000G for wet applications, enabling the measurement of larger samples of polydisperse materials. The Hydro MV is an alternative to the Hydro 2000S for smaller sample quantities, facilitating less consumption of high-cost organic dispersants and samples.
