SALD-MS Series

SALD-MS Series Multifunction Sampler for Shimadzu SALD Series

The most basic or most typical means of measurement used in laser diffraction particle size analyzers is circulation measurement. Circulation measurement is achieved on the SALD-2201 and SALD-7101 by the SALD-MS series multifunction sampler. As shown in the configuration and structure figures below, particle size distribution is measured while the particle group dispersed in liquid medium is circulated between the dispersing bath in the multifunction sampler and the flow cell located inside the measuring unit (optical system). Even when measuring samples having a wide distribution width on a multifunction sampler, it is less likely to be affected by sampling error since a relatively large amount of sample is measured. Another feature of a multifunction sampler is that it is less likely to be affected by sedimentation of particles even when measuring samples having a relatively large particle size or large density since the sample is circulated during measurement. Even when a sampling unit such as a batch cell that can accommodate smaller sample amounts is adopted, ultimately the measurement results obtained by using a multifunction sampler are the basis for selection of a sampling unit.

Configuration and Structure of Measuring Unit (Optical System) and Multifunction Sampler

Features

1) Wide variety of functions incorporated
The dispersing bath incorporates a stirrer and an ultrasonic oscillator. The dispersed suspension is delivered to the flow cell by a circulation pump. The circulation pump is designed specially to ensure that the particles, not just the liquid medium, are correctly circulated. Moreover, it can be connected to a PC so that the circulation pump, ultrasonic oscillator, liquid medium supply pump, etc. can be directly controlled (connected to serial port). A switch panel also is provided to enable control by manual operation.

2) Almost any organic solvent can be used
Almost all organic solvents, as well as water or ethyl alcohol, can be used as the liquid medium. (See Table 1.) A variety of liquid medium can be selected according to the measurement target and purpose.

3) Built-in liquid medium supply pump
The sampler has a built-in liquid medium supply pump. Liquid medium can be easily supplied automatically simply by inserting a tube connected to the liquid medium supply pump into a commercially-available PVC tank.

* A flow cell is provided on the multifunction sampler. Though the basic configuration and structure of the multifunction sampler are the same, the body color and type of flow cell provided on the SALD-2201 and SALD-7101 are different.

* The SALD-MS31 standard sampler (P/N 346-63701-10) for the SALD-3100 incorporating a more powerful circulation pump to achieve a measurement upper limit of 3000 ┬Ám (i.e. 3 mm) is also available for the SALD-3100.

* An exclusive pump is provided on SALD-200V ER Model-2 and SALD-300V Model-2.

Caution: Do not use highly-flammable organic solvents. They are dangerous. When highly-volatile organic solvents are used, be sure to provide adequate ventilation.
 

* Appearance and specifications are subject to change without notice.
