Why we have to do the stabilization of electronic instruments like UV, HPLC?
Electronic sensors can be extremely temperature-dependant. The reason is that electronics are semiconductors, and these devices work on the principal of electrons migrating from one area to another in the chip. The warmer the chip, the easier it is for these electrons to move across the “junction boundaries.” At any given temperature, it takes a certain voltage for the electrons to migrate. Increase the temperature, and more electrons move across the bopundaries for the same voltage, or conversely a lower voltage moves the same number of electrons across a warmer boundary. Since all electronic sensors use these voltage and current values to represent whatever it is that they are sensing, changes in the performance of the sensor electronics appear as offsets or other errors in the readings. In order to avoid these wrong readings, the temperature-sensitive electronic parts of the instrument are encased in what are often called “ovens” where they are heated to a controlled temperature, an
