Hi Kavya: What you have are not glitches but shifts in the absolute absorption probably due to bubbles or droplets moving through the beam. You can tell these from crystal glitches because the glitches are sharp and occur at the same energy in every scan while these are likely to move around from scan to scan. In my experience, this kind of change in the spectrum is not correctable. Hopefully you have lots of scans and only some of them have these artifacts and can be thrown out.
