1D basic KAMIKA method

Our measurement method is based on the  theory of geometric optics and relies on the measurement of transmitted light in the parallel beam of light. Particles move in liquids or in air. Their presence in the measurement zone, due to the phenomenon of light scattering, impairs the light beam received by the photodiode. This impairment is reflected in the amplitude of the electrical signal which is formed by the electronic system.   The amplitude of the impulse corresponds to the maximum dimension of the particle in spherical calibration. After the sieve calibration consistent with Elsieve, a set of particles can be presented according to the method used during traditional measurement on the mechanical sieves.

Principle of the measurement in the parallel beam of light is shown in the picture below:

 

 

The transmitter emits light in the range of near infrared through the A, B optical systems that form the measurement zone. The size of the measurement zone can be adapted to specific needs, and therefore we are able to measure particles of any size.

 

Signal is processed digitally with the use of converter A / C IPS  USB at a frequency of 500 kHz and a resolution of 12 bit. Depending on its size, each grain passing through the measurement zone is scanned from a dozen to several hundred times. Such frequency of the converter enables to determine amplitude of the impulse with the accuracy up to 1%, which also applies to the precision of the measurement of the particle size (its maximum dimension). 

 

Using KAMIKA method enables to measure all the particles from the sample, therefore every particle, even the biggest one is included in the results and presented in the distribution. Measurement is high-speed and digital - particles are measured one by one. The measurement of each individual particle can be seen on-line on a computer screen in the supplied software – Oscilloscope:

 

 

Such solution makes the process of feeding the particles crucial to the measurement. Its principles are explained more precisely in the descriptions of particular analyzers.

 

Reference materials of sphere particles Duke Standards are used to calibrate each analyzer in compliance with standards and atests of Thermo Fischer Scientific Inc. USA.

Calibration measurement using a spherical pattern looks like this:

 

 

 

KAMIKA is the owner of precise algorithms, that can be used to calculate the amplitude of an impulse into corresponding maximum diameter of the particle and determine calibration curve.

 

 

By means of the operational amplifier calibration curves are set for each of the 3 remaining ranges.

 

 

Calibration curve is described with complicated algorithm and close to 0 it has non-linear form.

 

 

This calibration saved in the computer's memory enables to perform high-speed and accurate measurements of the particles' size with the accuracy up to 5%. Calibration of every analyzer is confirmed with a certificate that is valid for one year. When a year passes it is recommended to recertificate the device and perform service works.
