Title: Why use Mass Spectrometry


1
Why use Mass Spectrometry
In 1998 there was the discovery of contaminated
food grade gas supplied to a large drinks company
organisation in the UK. This cost the
organisation in excess of 10,000,000 USD. The
source of contamination was traced to a UK
supplier that produced a large amount of CO2 as a
bi-product of the manufacture of Nitrate
Fertilizer. There was no on-line monitoring of
the process which is why the supplier company
installed an integrated Mass Spectrometer system
from ESS to ensure that this did not happen
again.

Real Time Monitoring
Real time monitoring was applied to the process
using Mass Spectrometry. Sample points were
connected to various parts of the plant to
closely monitor the process at every stage. The
data was reported to the plants main computer via
parallel links so automatic decisions could be
made. Data was stored so now quality records of
gas production were created on a minute by minute
basis. Mass Spectrometry gave the plant operator
the ability to measure many different gas types
if required.

Ammonium Nitrate Plant
Main Products Produces 500,000 tons of Ammonium
Nitrate Fertilizer/ year. Produces over 400 tons
of Liquid Co2 / day. Major Raw Materials Water,
Air, Natural gas, electricity and blended
fertilizer raw materials.
