Boiler condensate colour

[Swede74]

Hi All
New to the forum and would like some advice regarding flue gas condensate colour please.
Carried out a repair this afternoon and checked flue gas .
c02 in line with manufactures instructions and clean on the c0 side of things .
Upon completion emptied my analyser trap and noticed the condense was a pinky red colour .
Is this normal as I have never noticed this before , always been clear ( ish )
I will attach a photo

Many thanks

Swede

@ShaunCorbs could this be due to the hydrogen sulphide content in mains gas?
I’ve come across yellow and red sulphur deposits on oil boilers and that’s because they used to have a high sulphur content, which was a good lubricant on the pumps.

Could be or could be close to a main road and heavy traffic fumes being sucked into

I know hydrogen sulphide is added to mains gas and why but never heard of this before. Usually the concentration is small
