Spectronic Analytical Instruments has supplied a BWB XP flame photometer to Fujifilm Imaging Colorants (FFIC), an inkjet dye manufacturer, for use in its Process Technology Department.
FFIC provides colorants for inkjet printers, coloured chemical toners for laser printers and copiers and infrared absorbers for a range of speciality applications.
The BWB XP flame photometer employs modern technology to determine the concentration of certain metal ions, including sodium, potassium, lithium, calcium and barium.
It carries out a controlled flame test with the intensity of the flame colour quantified by photoelectric circuitry.
FFIC uses the flame photometer to carry out metal-ion exchanges and its use allows the determination of the degree of conversion of the metal ion.
This is said to be important for the solubility of the dye.
Gary Cuthbertson, the development chemist in FFIC's Process Technology Department, said: 'The BWB XP flame photometer allows us to continue to measure our own generated customer samples.
'Although we always have access to our Analytical Department and means of metal analysis, having the ability to do this locally prevents any delay in testing.
'It was the capabilities of the instrument that first drew us to it, the key thing being the ease of calibration of the instrument and its ability to carry out multiple metal-ion calibrations and to retain this within the instrument,' he added.
