Agilent Flame Photometric Detector (FPD) Parts
In 2005, Agilent released an improved FPD with minimum detectable levels (MDL) of 3.6 pg/s for sulfur and 60 fg/s for phosphorus. This is more than a 5 times improvement for sulfur. The updated design is based on a one-piece, deactivated transferline jet assembly and improved optics. Upgrade kits are available.
Managing gas purity; contamination from column bleed, sample residue, and corrosion; and air leaks can help keep your FPD at peak performance.
- The FPD uses three gases: air and hydrogen to support the flame, and nitrogen makeup for capillary
columns. The flow rates are critical for optimizing performance.
