    Bubbles enter the detector's flow cell, they can cause erratic baseline readings and loss of sensitivity. By placing a back pressure regulator (BPR) after the detector, the fluid remains under sufficient compression after leaving the column to prevent most bubbles from forming and thus helping to ensure a smoother baseline and increased sensitivity.
