Density of solids with statistics

This application determines the density of solids using the buoyancy method and the formula with correction for wires and air buoyancy. It supports the measurement of water temperature with temperature sensors, if such a sensor is connected to the balance. The sample is first weighed in air and then submerged in liquid. Based on the two weight values the application calculates the sample density. The Density of solids with statistics application uses the following calculations:

  • The density of water or ethanol is calculated with the Horner scheme at current temperature
  • Density of liquid: RhoLiq = RefLiq  / (1.0 + BCoeff * (TempLiq - 20.0))
  • Density kit correction: CorrDk = 1.0 - 2.0 * ( 0.7 * 0.7 ) / ( 76.0 * 76.0 ) | YDK03MS or YDK04MS
  • Free density kit: CorrDk = 1.0 - NumWir * (DiaWir * DiaWir) / (DiaVes * DiaVes) | NumWir =  Number of wires, DiaWir= Diameter of wires, DiaVes = Diameter of vessel
  • No density kit, no correction: CorrDk = 1.0
  • Air density correction: CorrAir = 0.0012 | Default value. This parameter can be edited at createTask and startTask
  • Sample density: Rho= fabs((wgAir * (RhoLiq - CorrAir)) / ((wgAir - wgLiq) * CorrDk) + CorrAir)
  • Sample volume: Vol = (wgAir - wgLiq) * dCorr * CorrDk / (RhoLiq - CorrAir)
  • Sum of all weight values: sum = ( n * initValue ) + sumComp | sumComp = sumComp + addValue; addValue = x comp. - initValue; initValue = first comp.
  • Average mean weight: avg = initValue + ( sumComp / n )
  • Standard deviation: dev = sqrt ((n * sum2Comp - sumComp * sumComp) / (n * (n-1))) | sum2Comp = sum2Comp + (addValue * addValue)
  • Variation coefficient: var = abs (dev / avg * 100)
  • Difference between min. and max.: diff = max. – min.

Density of liquids    

The application determines the density of liquids using YDK03MS or YDK04MS with glass plummet. It supports the measurement of water temperature with temperature sensors, if such a sensor is connected to the balance. In the first step the glass plummet is fixed on the frame of the density kit, placed in the center of a glass vessel and the setup is tared. In the second step the liquid to be measured is filled in the glass vessel until the glass plummet is covered and the weight is measured. Because of the buoyancy the glass plummet weight in liquid is a negative value and from this negative weight the liquid density is calculated. The application density of liquids uses the following calculations:

  • Air buoyancy correction: paramCorrAir = 0.0012
  • Volume correction: dCorr = 1.0 - (paramCorrAir / 8.0) | Calibration weight density = 8.0 g/cm3
  • Liquid density: paramRhoLiq = fabs(wgLiq * dCorr / paramVolPlum) | wgLiq = negative weight in liquid

Density with pycnometer

This application determines the density of powders, liquids and pasty substances using a pycnometer. It supports the measurement of water temperature with temperature sensors, if such a sensor is connected to the balance. The sample is first weighed in air and then submerged in liquid. Based on the two weight values the application calculates the sample density. The Density with pycnometer application uses the following calculations:

  • The density of water or ethanol is calculated with the Horner scheme at current temperature
  • Density of liquid: RhoLiq = RefLiq / (1.0 + BCoeff * (TempLiq - 20.0))
  • Density kit correction factor: CorrDk = 1.0 | Default value
  • Air density correction: CorrAir = 0.0012 | Default value. This parameter can be edited at createTask and startTask
  • Weight of residual liquid: wgRes = wgResTmp + wgTmp
  • Sample density: Rho = fabs((wgAir * (rhoLiq - corrAir)) / ((wgLiq + wgAir - wgRes) + corrAir)

Backweighing

The Backweighing application is used for simple differential weighing with lot tracking (alphanumeric). First the initial weight (with tare) is measured and then up to three back weights per sample. The application calculates the difference between the initial and back weight of samples. The application uses the following calculations:

  • Weight residue: residue = netBackWeight = grossBackWeight - panWeight
  • Percent residue: residue [%] =(netBackWeight / netInitialWeight )* 100 | default decpoint = 2
  • Weight loss: loss = netInitialWeight - netBackWeight
  • Percent loss: loss [%] = ((netInitialWeight - netBackWeight) / netInitialWeight)* 100 | default decpoint = 2; if loss[%] < 0.01% --> display/print "< 0.01%"  (string)

Residue on ignition    

The application residue on ignition is used to determine the sample initial weight, back weight and residue on ignition. Based on the first back weight, the remaining substance weight (rest) before drying is determined and based on the second back weight the residue on ignition after drying. The first and second back weighings can be repeated as often as desired and previous back weights overwritten, and the most recent values are always used by the software to calculate the rest and the residue on ignition. The application is using the following calculations:

  • first backweighing: residue = netBackWeight1 = grossBackWeight1  panWeight
  • second backweighing: ignition = netBackWeight2 = grossBackWeight2 - panWeight.
