a solution has gluten concentration of 2000ug/mL at 150uL. if 2uLof that solution is taken out what is the quantity of gluten in ppm?
I'm confused. If it has a concn of 2000 ug/mL, what's with the 150 uL. Are you diluting the 2000 ug/mL soln by taking 2 uL an diluting to 150 uL?
no i think we don't need to use 150ul.. can u solve it without using 150ul?
2000 ug/mL = 2000 ppm whether you have 1 mL or 10 L
