man... i was counting grains in a spoonfull and dividing in half
... i tried using a Ca selective eletrode a couple of years ago... that thing drove me crazy.. i got a feeling i will be measuring out those blue spoons for years to come
what some needs to invent is the robot to use the sali-kits for ya... now theres an invention... but then again.. that just takes all the fun outta being a hobbyist
thanks for the info about the 1/2 spoon-thing
