Hello all, Our daily check sample for the Minispec mq40 has been decreased in volume due to probably evaporation!! Anyone knows what solution it is and whether we can just make the same sample in a chemistry lab or we have to buy it? This code is written on the daily check sample: E145299 Thank you in advance, Amin asked Apr 05 '13 at 03:55 Amin os |
