Instrument: pH Sensor

Dataset: 
CO2-stressed diatom proteome
Instrument: 
pH Sensor
Instrument Short Name: pH Sensor
Instrument Description:

An instrument that measures the hydrogen ion activity in solutions.

The overall concentration of hydrogen ions is inversely related to its pH.  The pH scale ranges from 0 to 14 and indicates whether acidic (more H+) or basic (less H+). 

PI supplied instrument name: pH electrode (Thermo 9106BNWP)
Dataset-specific description

A gel-filled combination pH electrode (Thermo, 9106BNWP) was mounted through the wall of a 1L polycarbonate bottle using a bulkhead mount. The electrode potential was monitored using a pH relay (Eutech Inst., pH200 controller).
