LTCC based microfluidic optical detector

A new fiber-based optical microfluidic detector was designed for low-volume sample measurement. Microdetector was fabricated by use of LTCC (low temperature co-fired ceramic) technology. The microdevice was made as separate module, which can be connected via tubing to any microanalytical system. The designed detector allowed to measure an optical absorbance (transmittance) in the analytical channel. Presented microfluidic detector can be also applied as a part of integrated muTAS (micro-total analysis system). The preliminary tests indicate linear absorbance detection in the range 9.5-28.5 mug/ml of cochineal red A and 10-20 mug/ml of sunset yellow in the test solutions
