Environmental conditions

Indoor use, normal laboratory environment

External temperature

20° to 23° C (68° to 73.4° F)

Relative humidity

Less than 80% (no condensation)

Detection wavelength

214 nm (other wavelengths available; compound chromophore does not have to be in proximity to ionization center)

Detection sensitivity

5–10 μg/ml (ppm) depending upon chromophore; typical working concentration 50–100 μg/ml

Sample volume required

50 μl/sample well (min. 20 μl/well); 24 wells per 24 pH analysis; 12 wells per 12 pH analysis

Sample format

Typical DMSO concentration 0.1–0.2% (v/v); higher DMSO concentrations tolerated at higher wavelengths

Maximum sample throughput

12 compounds/h for 24-point aqueous pKa measurement (pKa PRO™ 96XT)

Sample purity requirements

Compound of interest should be the major species present; impurities and degradants can often be separated
