96-channel simultaneous acquisition technology

Each particle size analyzer is equipped with a detector that has multiple independent channels to detect the scattered light from the sample. The scattered light signals are converted into electrical signals by the detectors and then analyzed by software to generate a particle size distribution spectrum. With advances in technology, in recent years, particle size analyzers have increasingly more optical channels—many models now feature as many as over a hundred channels. As for other brands' claims about the motherboard's sampling rate being so many times per second, each channel is sampled sequentially: only after the first channel has been fully sampled does the instrument move on to the second channel. Although it takes only a short time to complete the sampling of all over a hundred channels, the total sampling time remains quite long when compared to the constantly changing nature of the sample itself. As a result, the signals collected in this manner do not represent an instantaneous spectrum across all channels, and the resulting particle size distribution is therefore not highly accurate. NKT’s 96-channel simultaneous acquisition motherboard breaks through the limitation of sequential sampling. After the software issues the sampling command, all channels instantly freeze and collect data simultaneously—just like taking a photograph—to ensure temporal consistency of the spectra across all channels, thus delivering more accurate data.

With advances in technology, in recent years, particle size analyzers have increasingly more optical channels—many models now feature over a hundred channels. As for other brands' claims about the number of times the mainboard can collect data per second, without exception, they perform channel-by-channel acquisition: only after completing the first channel's data collection do they move on to the second channel. Although the total time required to acquire data from all over a hundred channels may seem short, compared to the constantly changing nature of the sample itself, the actual data acquisition period turns out to be quite lengthy. As a result, the signals collected in this manner do not represent an instantaneous spectrum across all channels, and the resulting particle size distribution is therefore less accurate. NKT’s 96-channel simultaneous acquisition mainboard breaks through the limitation of sequential sampling. Once the software issues the acquisition command, all channels instantly freeze and collect data simultaneously—just like taking a photograph—to ensure temporal consistency of the spectra captured across all channels, thereby delivering more accurate data.

Effect

Automatically adjusts the optical path to ensure that the instrument’s optical system is in perfect condition, guaranteeing the accuracy and repeatability of the tests.

After the instrument vibrates, the optical system quickly returns to its original position.

Simplify the tester’s operation process and facilitate instrument maintenance.
