Crystal form of pyridopyrimidine derivative and preparation method thereof

The present invention relates to crystal forms of an oxypyridine amide derivative and a preparation method therefor. In particular, the present invention relates to crystal forms A, B, C, D, E and F of a compound represented by formula (I) and a preparation method therefor. The crystal forms of the compound represented by formula (I) as described in the present invention have good crystal form stability and may be better for clinical use.

Crystal forms of oxypyridine amide derivative and preparation method therefor

A novel light-assisted quartz crystal microbalance and a measurement method thereof. The microbalance comprises a QCM/QCM-D chip, an oscillation circuit, a frequency counter, a computer, a reaction chamber, and a light source. Light emitted from the light source is able to irradiate a surface of the QCM/QCM-D chip. By additionally configuring a light source with the ability to irradiate a chip surface, when irradiated the surface of the QCM/QCM-D chip changes properties thereof, and irradiation of the surface of the QCM/QCM-D chip greatly increases the resonance frequency. Correspondingly, irradiation of the surface of the chip also changes mechanical properties and piezioelectric characteristics of quartz crystal, thereby effectively improving measurement sensitivity of a quartz crystal microbalance apparatus system.

Light-assisted quartz crystal microbalance and measurement method thereof
