Fig. 7 shows an overlay of equally the sample UV spectra plus the common UV spectra for peak B when detected at 310 nm. The UV spectra from the compounds detected in the cosmetics are proposed to become the exact same compounds because the common compound as the two UV spectra coincide. Using PDA detectors can obtain a UV spectrum, making it possible for For additional responsible qualitative Assessment.
When the separated mild beam is acquired by a photodiode, which is a sequence of 1,024 photodetectors, only the wavelengths in the specified selection are transformed into electrical signals and processed as absorbance info. ＊Sometimes, this is referred to as a diode array detector (Father).
optional, MEB collection works by using air insulation under the premise of ensuring safety and balance, drastically minimizing the burden of MEB sequence to really make it more handy and functional, is really a low sounds ,large performance regular voltage and current energy provide.
