美国Cargille折射率标准液是非常稳定、无毒的液体,在不同的温度和波长下,折射率的测量精度可达+/-0.00005。这些折射率测量的异常高精度通常要求用户知道他或她的工作温度,精确度为+/-0.02℃或更高;这是因为液体的温度系数通常为每1摄氏度-0.0004折射率单位,所以每0.02摄氏度的温度差将影响大约0.000008的折射率单位。
当主校准液的折射率距离为20℃或以下时,用户可以计算一个温度系数,并计算(插值)其中任意温度的折射率,精度至少为+/-0.00006(折射率与温度的关系接近线性)。典型的温度系数(精确到+/-10%)可从Cargille实验室获得,在实践中,可用于校正从校准温度到已知温度变化0.20℃的最高温度。所有测量都是NIST (NBS)可追踪的。所有可用的测量都列在Cargille的高精度液体产品页面上。
