Capacitive sensor system for measurement of temperature and humidity
Dielectrical glass-ceramic materials for capacitive sensors to measure temperature and humidity have been developed. These sensors are suited for temperature measurement between 4.2 and 100 K (low temperature range), but also for temperatures up to 573 K. The measurement of gas humidity is possible between 5 and 95% R.H. The sensors can be used in multicomponent …

Analytical Chemistry
So, for example 1, it states that an uncalibrated pipette is used in the titration of 25 mL of 0.250 molar potassium permanganate with 50 mL of nitric acid. If the pipette delivers 23.120 ± 0.02 mL, what can be said about the possible errors observed?Alright. So, typically when they give us a pipette, it''s supposed to be calibrated.
1.1: What is Analytical Chemistry
The craft of analytical chemistry is found not in performing a routine analysis on a routine sample—a task we appropriately call chemical analysis—but in improving established analytical methods, in extending these analytical methods to new types of samples, and in developing new analytical methods to measure chemical phenomena [de Haseth ...
