Anyone can help with my question

Hi, it is not a pressure profile , its a detector board temperature with 0.01C range. 

thank you for the reply.

when we  run samples, we sometimes got really weird things. can you help me further what the problem could be. the picture below is just a water sample

also the following picture looks similar to the pattern shown in my first question? 

this one is a brine water sample

is it because we run brine water on HPLC and it has caused the system too dirty? 

thanks so much

Please click on   I can't tell everything you are looking at.  The window will tell you what the signals are and the ranges.  Blue and red are pressure?  and looks like it's in a run?

thank you for the useful information
