Advanced Package QP2

Density of Solids

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))

Filter particulate matter

This application is used for the differential weighing of filters with individual sample ID. During the process the initial and back weighing of filters is performed and difference between the initial and back weight of each filter is determined.

Furthermore the application creates a statistics for a batch of filters by calculating the average, standard deviation, minimum and maximum particle load. The application uses the following fomulas:

Averaging with Backweigher

This application is used for moving samples (e. g. living animals) and for weighing in unstable environments.
