To EA users,

Is there somebody who is participating in IPE-WEPAL and ISE-WEPAL 
proficiency testing?
Our laboratory is participating in this proficiency testing in total NC of 
plant in soil. Unfortunately, we are having low recovery in Total C of two 
of four samples they are giving to us. I dont know if we have a combustion 
problem or drying method problem. If you are one of the participant, can 
you send me your method for me to compare with our method.

Thanks
Ruben
