    Finally an clearly explenation of the supressor. Thank you Robin Stoodly

      not sure if you guys cares but if you're bored like me during the covid times then you can stream pretty much all the latest series on Instaflixxer. Been streaming with my girlfriend for the last couple of days =)

    Thanks for all your videos. It was very helpful to refresh my knowledge before the job interview.

    Thanks for the animated explanation how it works. Also, where exactly the Deionized Water comes in to play in suppressor ?

    • @robinstoodley9431

      The suppressor has three chambers. At any given time, eluent flows through one, sulfuric acid through another, and deionized water through the third. The role of the chambers cycles periodically (every ~10 minutes). The eluent one becomes the acid one, the acid one becomes the water one and the water one is brought into use with the eluent. The one flowing eluent is doing the suppression, the one flowing acid is regenerating, and the one flowing water is rinsing away excess sulfuric acid (to get it ready for it's next role suppressing the eluent conductivity).

    Why we run a blank in ion chromatography

    • @robinstoodley9431
      @robinstoodley9431  3 ปีที่แล้ว +1

      To check for the possibility that the solvent (deionized water typically) that you used to make calibration solutions (standard solutions) contains any of the ions that you are measuring.

    how is this instrument calibrated? what one needs to calibrate it?

    • @robinstoodley9431
      @robinstoodley9431  5 ปีที่แล้ว

      Absolute calibration of the conductivity detector is done at the factory and normally does not ever need re-doing. Relative calibration done daily by measuring a blank sample; perhaps deionized water.
