Preventative maintenance can save labs money in the long run, but many analysts don’t perform this critical step as frequently as they should due to economic or scheduling concerns. We wanted to reduce the cost of maintenance so that customers had the opportunity to prevent problems through more frequent routine maintenance of their Agilent GC inlets. Since the inlet is where GC system failures occur first, especially with dirty sample introductions, regular maintenance can prevent unexpected downtime and costly sample reanalysis. We recommend that customers replace the GC septum, the GC inlet liner, the liner O-ring, and the inlet bottom seal simultaneously when doing preventative inlet maintenance. By developing a seal that can be used twice, we make preventative maintenance more economical for our customers.
