SALD-7101 PDF-Dokument 1.8 MB

The SALD-7101 is the first in the world to adopt a 375 nm UV semiconductor laser. This provides a great new tool for research and development in nanotechnology and life sciences.

Features

10 nm Lower Limit of Detection
A previously unreachable 10 nm lower limit of detection is achieved through a combination of a world-first 375 nm-wavelength UV semiconductor laser light source and a light sensor consisting of a high-sensitivity light receptors created by the most up-to-date production processes specifically to handle UV lasers.

Measure Concentrations from Several ppm to 20%
Compared to other instruments, SALD-7101 permits measurements across an extremely broad range of concentrations from several ppm to 20%. The particle size of fine particles, particularly nanoparticles, varies with the concentration. The dispersion and coagulation of nanoparticles can be observed while altering the concentration.

1-second Minimum Measurement Time
The standard setting for the measurement time is 10 seconds but can be reduced to a minimum of 1 second. The particle size distribution can be displayed in realtime at 1-second intervals. This function is permitted by the use of a single light source that requires no switching and the wide-angle detection method.

SLIT Optical System
Seamless measurement over the entire range using a single measurement principle, single optical system, and single light source. The SLIT optical system continuously captures forward-scattered light at up to 60° on a single detection plane. Accurate particle size distribution measurements are possible across the entire measurement range using a single standard, as the instrument does not incorporate multiple optical systems that create discontinuities in the data.

Software

The WingSALD-7101 for Windows 2000/Xp combines a variety of data processing functions with simple and quick operability. The software is divided into three "wings" (subprograms) to suit different purposes and processing requirements.

Particle size distribution data and light intensity distribution data can be displayed in real time. This enables the real-time monitoring of changes in the sample and the dispersion state that occur over time. In particular, the real-time display of particle size distribution data is a unique feature of the SALD-7101. Changes from the 100¼m level to the 10 nm level and changes from the 10 nm level to the 100¼m level can be observed with complete continuity in terms of both time and particle diameter range.

Statistical processing, time-series processing, 3D processing, and overlay graph of particle size distribution data is possible for up to 200 data items.
