Having a car alarm that goes off 15 seconds after a break-in puts you at risk of property damage and significant loss. If you wouldn't take this risk with your car, why take it in your process plant?
If you're using an extractive oxygen analyzer that requires sampling and conditioning to prevent explosive conditions, that's exactly what you're getting - an alert up to 60 seconds after an oxygen build up is started. Using an extractive analyzer that requires sampling and conditioning means it's impossible to get real-time information. Measurements are delayed by up to a minute as the sample travels through pipes to the analyzer. In addition oxygen in the sample can be diluted by the gas ahead of and behind it, resulting in a falsely flat excursion curve. An alarm threshold may not be met when it should, so you get one, perhaps inaccurate, result in one minute.
Eliminate the risk. Get continuous real-time measurement. The GPro 500 tunable diode laser gas analyzer from Mettler-Toledo measures in-situ, without the need for sampling and conditioning. It provides continuous measurement and safety-critical applications, so you'll know about oxygen excursions immediately. Don't leave your plant safety up to delayed measurement. Rethink safety. Rethink gas analytics.
