Laser Diffraction Particle Size Analyzer
L as e r Di ffr ac t i o n P a r t i c l e S i ze An a ly ze r
Designed for Measurement of Coarse
F e a t u re s
The SALD-3101 is useful wherever there is a need to measure coarse or dense particles, in such fields as metals,
minerals, pharmaceuticals, chemicals, environment, river conservation, disaster prevention, civil engineering,
construction, agriculture, and soil.
Seamless Coverage over a Wide Measuring Range
from 0.05 to 3000µm (3mm)
Seamlessly covers an extremely wide range of particle
diameters from 0.05 to 3000µm using a single
measurement principle, a single optical system, and a
single light source. Always achieves accurate particle
size distribution measurements across the entire
measuring range using a single standard, without data
discontinuities from a multiple optical system
Powerful Particle Circulation Mechanism
The sampler incorporates a powerful vertical radial
pump with a flow rate of 5000 cm3/minute to reliably
circulate coarse or dense particles from several hundred
microns to several millimeters in size. This powerful
particle circulation is the key technology behind the
3000µm (3mm) upper measuring limit.

Particle Size Distribution of
Star Sand
(Wet Measurement)
Normalized Particle Amount
TWO types of fossil Foraminifer recoverd from Iriomote-jima Island in Yaeyama archipelago located south west of
Japan are known as "Sun Sand" and "Star Sand". Sun Sand is coarser than Star Sand. The Shimadzu SALD-3101
Laser Diffraction Particle Size Analyzer accurately determined the small difference in the particle sizes between Sun
Sand and Star Sand.

Dry Measurement Units
These units measure the particle size distribution of a sample powder dispersed in the air.
Use these units for patricle size distribution measurements of powders with no suitable dispersion medium
and powders that dissolve in liquids.
Two unit types are available to suit the sample state and measurement aim.
•SALD-DS21 Injection type Dry Measurement Unit (measuring range: approx. 0.8 to 1000µm)(P/N 347-60100-20)
Sample powder is dispersed for measurement by injecting in the air from a nozzle.
The unit offers three types of sample suction mechanisms and three types of nozzles, which allow setting of the optimal
dispersion force and sample volume conditions to match the sample state and aim of measurement aim.
•SALD-DS3 Free-fall type Dry Measurement Unit (measuring range: approx. 10 to 3000µm)(P/N 346-612060-20)
The Sample is measured during free fall.
Even easily damaged particles can be directly measured.
A separate dry-measurement detector case (P/N 347-60010-20), compressor (SALD-DS21 only) and dust collector are
required to use the dry measurement units.
SALD-AC30 Acyclic Monitor Sampler
(P/N 346-83746-02)
Completes one measurement cycle including washing, in 30 seconds. Automatically detects infused sample to start
measurement and data storage.
The rapid measurement time saves effort and makes this the optimal unit for measuring a sample with a rapidly changing
particle size distribution, such as powder undergoing a grinding process.
