Any suggestions ?

Probably your gas strut is now merely a strut, having lost its gas.

#1 New chair. These things aren't fixable, aren't intended to be
fixable.

#2 New gas strut. Unless you're buying containerloads from China, new
struts from strut shops cost more than a new chair from Viking.

#3 Another gas strut from another chair. Good fix in offices, as
there's usually a gradual attrition of chairs for different reasons
and you cna find spares.

#4 Convert it to a mechanically clamped chair, rather than a bouncy
strut. If it's your chair, and your chair alone, this isn't a bad
thing.

The fourth option is the one I took with my chair. I found a bit of
metal tube which fitted round the extending stem of the strut[1], thus
stopping it from collapsing. The chair is now permanently at its max
height - which is where I want it.

[1] ISTR that I had to remove and replace the end fixing of the strut in
order to slide the tube over the stem. A bit fiddly, with some sort of
spring clip - but do-able.
