Questions regarding ANTEK’s ultraviolet fluorescence sulfur analysis! ! ! Urgent
Thread Content
When creating a standard curve for ultraviolet fluorescence sulfur detection, standards are used in mg/L units, with 10 ul of sample being applied and a density value of 1 entered. For sample analysis, however, results need to be presented in mg/kg units; therefore, when entering the sample data, the density value should reflect the actual density measured at room temperature, with the sample volume remaining at 10 ul. Now the question is, if I use standards in mg/kg units to create the standard curve, what should I do with the density value? ? ? ?
Can’t I even do this kind of conversion by myself? The product of volume and density is weight; you can then do the conversion yourself.
Of course it will. The problem is that our instrument uses 10 ul per injection; previously the standard samples were expressed in mg/L, but now they are expressed in mg/kg

Just convert the volume in the denominator to weight, right? So why is there still a problem? Without density data, won’t you measure it yourself? Wouldn’t it be wise to ask the manufacturer of the standard sample about its density? This is no longer a math problem.
The curve is in mg/kg; since the desired result is also in mg/kg, I think there’s no need for unit conversion. Just turn off unit conversion or write it down
