Going beyond the single nano region and into the sub-nano region, the IG-1000
uses the induced grating (IG) method, which is based on a new principle for measuring
the size of nanoparticles using the phenomenon of dielectrophoresis and diffracted
light, to provide excellent reproducibility and the acquisition of stable data,
particularly for sub-10 nm particles. The IG method does not use scattered light,
is free from physical restrictions and does not require the input of the refractive
index as a measurement condition. As a result, the IG-1000
can measure the size of nanoparticles simply and with high sensitivity, and is
particularly effective for the analysis of single nanoparticles.
Features
- High-Sensitivity Analysis of Single Nanoparticles
Stable measurement with good reproducibility is possible because the IG-1000
utilizes optical signals emitted by the diffraction grating formed by the
particles, and not scattered light emitted by the particles. Even in the single
nano region, a good S/N ratio can be obtained.
- Resistance to Contamination
This new measurement principle is resistant to contamination and, even if
the sample is mixed with small amounts of foreign particles, information about
the particles to be analyzed is captured reliably. The filtering of samples
in order to remove coarse particles is not required.
- High Reproducibility
The IG method ensures high reproducibility and the acquisition of stable data.
In particular, high reproducibility for particle sizes of less than 10 nm
removes the uncertainty of particle analysis in the single nano region. The
viewing of the raw data of diffracted light is also possible, enabling a simple
approximate validation of measurement results.
- Simple, Three-step Workflow
With the IG-1000,
analysis is easy: inject the sample, insert the electrode and begin analysis.
Using the IG method, it can measure particles in the 0.5 to 200 nm range in
about 30 seconds, from measurement start to displayed results.
