What type of data transfer can be executed by the DMA 35 version 3?
IrDA
How is TPO calculated on the TPO 5000?
Headspace Oxygen (HSO) + Dissolved Oxygen (DO)
Which polarimeters can use Type 1 sample cells/QCPs?
All of them. The cells are downward compatible but not upward compatible (Type 2 cells can not be used on the MCP 150/4100/5X00).
What is the recommended temperature range of the SVM 3001 (in Celsius)?
-60 C to 135 C
What is the ASTM Method for Cleveland Open Cup flash point testing?
ASTM D92
Which Xsample is recommended to tackle high-throughput on a DMA 4501 + Alcolyzer 3001 + Haze 3001 system?
Xsample 520
On the DMA 4501 Diet, how often should you run a Process Water Adjustment?
Daily
Is the Abbemat 3200 compliant with 21 CFR Part 11?
No, the Abbemat 3200, 3100, and 3000 are not compliant with 21 CFR Part 11.
PTD 100 Cone Plate + CP measuring bob
What must the customer supply on their own when purchasing a RapidOxy 100/100 Fuel?
Medical grade Oxygen (>99.6%)
Pressure Regulator (10 bar)
Name a reason you might get a false-positive filling warning on a DMA
Non-newtonian
Inhomogeneous
Bad Air/Water reference
Name 2 reasons why a CarboQC/CboxQC CO2 measurement would differ from results from a manometer method (e.g. Zahm & Nagel)
Measured Temperature
Air in the sample
Altitude
Snifting (releasing overpressure in headspace)
Equilibrium
What value must you input if you want to output Specific Rotation on a polarimeter?
Concentration
A customer wants to measure the viscosity of a sample with a pH of 3, and they want to purchase an SVM due to the wide temperature range. Can we accommodate this request, and if so, how?
No, the SVM can handle slightly more acidic or basic samples with a chemical upgrade, but this high acidity would prove incompatible with the metal components of the instrument. Try to sell a Lovis or ViscoQC.
For ASTM D86, which group should be used for Diesel samples?
Group 4
Why would you need to add a polarimeter rather than a refractometer to your Modulyzer system when measuring liqueurs?
If the sample contains sucrose and/or invert sugar, we will want a polarimeter. If the sample is opaque or has an alternative sweetener (e.g. HFCS) then we will want a refractometer.
Does the CarboQC/CboxQC directly measure package pressure?
No. Since the device is filled with overpressure, a direct measurement is impossible. The reported value is calculated based on the CO2-air mixture at equilibrium and should not be used as a QC measurement.
Why would a Brix value measured on a refractometer vary from a Brix value measured on a polarimeter?
Refractometers measure in %m/m, whereas polarimeters measure in %m/v
The Lovis 2000 M/ME directly measures
a) Dynamic Viscosity
b) Kinetic Viscosity
c) Both A and B
d) None of the above
What are the two other ways a customer may refer to the Penetration Units (PU) measured by the PNR 12?
1/10 mm or dmm
Why would you want to measure concentration in %w/w rather than %v/v?
Mass% (%w/w) is independent of temperature, whereas the volume of a sample may change.
A customer just bought a TPO for their new facility, and the installation went well. However, a week later, they called you saying that their TPO values did not match between facilities. They explained that they tested a package and then sent the same batch to the new facility to see how it compares, but it is reading too low. What is going on here?
If they are sending samples from the same batch from one facility to the other, there will be oxidation taking place between the two tests. The TPO results will be highest when the samples are fresh, and will decrease over time.
In addition to Pol (ºZ), name two of the three other values measured by the Betalyser.
Sodium
Potassium
Alpha-amino Nitrogen
Which of the following does not have bias correction from ASTM D7042 to D445?
a) Biodiesel at 40 °C
b) Base oils at 40 °C and 100 °C
c) Diesel Fuel at 40 °C
d) Jet fuels at -20 °C
B. There is no bias found for this sample type, so no correction is needed
What are the two cooling mode options on the Callisto 100? For an extra 100 points, which cooling mode is required for ASTM D6371?
Stepwise Cooling and Linear Cooling. ASTM D6371 requires stepwise cooling.
