Borosilicate glass is a type of glass with silica and boron trioxide as the main glass-forming constituents. Borosilicate glasses are known for having very low coefficients of thermal expansion (≈3 × 10 −6 K −1 at 20 °C), making them more resistant to thermal shock than any other common glass. Such glass is subjected to less thermal stress and can withstand temperature differentials ...

Packed Columns Supports
Packed Columns Supports. Supports hold stationary phases, and ideal supports are said to have no direct contribution to separations of samples. However, peak tailing and component decomposition sometimes occur due to the characteristics of a support. It is therefore necessary to choose an appropriate packing material for each analytical purpose.
