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.

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, the number of optical channels in particle size analyzers has been increasing steadily; many models now feature as many as over a hundred channels. As for other brands' claims about the motherboard's sampling rate—whether it’s several times per second or not—without exception, they still collect data one channel at a time: after completing the first channel, they move on to the second, and so forth. 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 acquisition time is still 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 not highly accurate. NKT’s 96-channel simultaneous acquisition motherboard breaks through the limitations of traditional sampling methods. Once the software issues the acquisition command, all channels instantly freeze and capture data simultaneously—just like taking a photograph—to ensure temporal consistency across all channels during signal acquisition, thus yielding more accurate data.
