2008年9月2日 · Re: converting ppb to ug/m3 we are measuring NO2 in air (ppb) as well as the pressure and temperature im not sure on the method of te measurement of the (NO2) we are using an ML9841B Nitrogen Oxides Analyzer ive looked in the manual but cann't find nything telling me if it is Mw or volume

2006年3月23日 · Listen when working with ug you are using the 1,000,0000 that's billion. This conversions are straight forward in this case just put the billion up and put the ug number under it. Or ug 221 is 1,000,000,000 221 when using the micro gram that part is to what ever it is to a billion. And this is all based on the kilogram or kg. or only 221 ppb.

2011年2月5日 · How do you convert 100 ug/m^3 to parts per billion? The molar mass of SO2 is 64.07 g/mol, so 100 µg is 1.56 µmol. For the cubic meter of mixture, you need temperature and pressure to determine molar volume.

2009年1月31日 · Hi, I'm working on a dilution curve problem, and need to convert mg/ml to ppb and ug/ml to ppb. Example: 0.016 mg/ml = ? ppb and 15.4 ug/ml = ? ppb

2006年7月5日 · On a weight/volume basis, it is 100 ppb or 0.1 ppm. (If the liter were water, it would weigh a kilogram). On a weight over weight basis, a liter of blood weighs about 1.06 kg, so it is 100 µg/1.06 kg = 94 ppb = 0.094 ppm

2008年4月8日 · Re: ppb to ug per 100 sq. cm Hi, can you give a bit more information about what you want to do

2006年12月18日 · ppb is the same as microgram/liter, so I find it easiest to just convert to that then call it ppb. 60 nanogram/microliter = 60000 microgram/liter = 60000 ppm 1 picogram/microliter = 1 microgram/liter = 1 ppb

2022年5月17日 · Hello, I need some help with the unit conversion from pmol/kg to ppb. For example, I have 28 pmol/kg of Lanthanum (138.91 amu) and 50 pmol/kg of Cerium (140.12 amu).
