Drying solvents while taking care of purity
There is actually a book on preparing laboratory chemicals you can look up:


  "Purification of Laboratory Chemicals" by WLF Armarego and CLL Chai


However, given that all the chemicals you want to dry are extremely hygroscopic, I'm not sure how long they would stay super dry for calibration purposes (and I'm not sure you need super dry solvents for calibration either). If you need it to last, you may need a large dry box.
