Hi Ewerton,
Welcome to the wacky world of EA maintenance! You'll experience this and
more as you learn the ropes.
Cracked glass (often in the EA itself), leaky fittings, spent O-rings;
twisted connectors; dead GC columns, you name it. It will happen.
Keep a log of what you've analyzed--number of samples and type. You'll get
a sense of which ones are problems (filters and rocks) and which are easy
(animal tissues and standards).
Isogeochem archives are a good place to refer to.
Have fun.
