研究了利用衰减全反射（ATR）太赫兹（THz）光谱定量测定乳腺炎的体细胞计数（SCC）。使用原料牛奶中控制SCC的样品，我们用傅里叶变换太赫兹光谱仪测量了它们在30e440 cm Ā1太赫兹区域的ATR信号。我们发现ATR信号随着SCC的升高而降低。此外，我们发现ATR信号与SCC之间的相关性在8.0 Â 104到1.57 Â 106个细胞/mL之间为139 cmĀ1 （R2为098）。这些发现证明了用单色太赫兹波检测乳腺炎的潜力。
Quantitative somatic cell count (SCC) measurement for detection of mastitis using an attenuated total reflectance (ATR) terahertz (THz) spectroscopy was investigated. Using samples with controlled SCC derived from raw milk, we measured their ATR signal in the THz region 30e440 cm Ā1 with a Fourier-Transform THz spectrometer. We found ATR signals decreased as SCC increased. Furthermore, we found the correlation between the ATR signal and SCC from 8.0 Â 104 to 1.57 Â 106 cells/mL was optimal at 139 cmĀ1 (R2 ž 098). These findings demonstrate a potential to detect mastitis with a monochromatic THz wave.
