Jon Eley, the three-time Olympian who was Britain's flagbearer at the opening ceremony, was eliminated at the semi-final stage of the men's 500m short track speed skating.
He subsequently came third in the B final to finish seventh overall.
"I'm very disappointed not to get to the final but I am pretty pleased with the way I have turned my season around.
"At Christmas I was struggling and didn't think times like this would come again.
"The past couple of days I have been skating better than I have ever skated before. I was feeling up for it, I skated beautifully in the quarter-final and it was just a slip in the semi-final cost me."
