Verify the blend where it is blended
A blend is certified by sampling the finished product. If the ratio was wrong, you find out after the whole volume has been made.
The measurement problem
Blending is a ratio problem, and ratio errors are systematic: a metering pump drifting by a few percent produces every batch slightly wrong in the same direction, and nothing in the process record shows it. The finished-product sample confirms the error but not its origin.
Measuring composition in line turns the ratio into an observable. A drift shows up as a slope on the concentration trace long before it becomes an out-of-specification certificate.
What a live reading changes
- Ratio confirmed continuously rather than certified retrospectively.
- Metering drift visible as a trend instead of as an eventual rejection.
- Homogeneity called on a plateau in spectral variance rather than on a fixed mixing time.
- Multiple units can run in parallel on one computer where several streams have to be watched at once.
Is this your measurement?
Send the stream, the concentration range and the decision it blocks. Where it makes sense we test on your own process samples first.
