What type of data transfer can be executed by the DMA 35 version 3?

IrDA

100

How is TPO calculated on the TPO 5000?

Headspace Oxygen (HSO) + Dissolved Oxygen (DO)

100

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).

100

What is the recommended temperature range of the SVM 3001 (in Celsius)?

-60 C to 135 C

100

What is the ASTM Method for Cleveland Open Cup flash point testing?

ASTM D92

200

Which Xsample is recommended to tackle high-throughput on a DMA 4501 + Alcolyzer 3001 + Haze 3001 system?

Xsample 520

200

On the DMA 4501 Diet, how often should you run a Process Water Adjustment?

Daily

200

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.

200
What accessory should you recommend for the ViscoQC if the customer has a very small sample size (less than 2 mL)?

PTD 100 Cone Plate + CP measuring bob

200

What must the customer supply on their own when purchasing a RapidOxy 100/100 Fuel?

Medical grade Oxygen (>99.6%)

Pressure Regulator (10 bar)

300

Name a reason you might get a false-positive filling warning on a DMA

Non-newtonian

Inhomogeneous

Bad Air/Water reference

300

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

300

What value must you input if you want to output Specific Rotation on a polarimeter?

Concentration


300

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.

300

For ASTM D86, which group should be used for Diesel samples?

Group 4

400

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.

400

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.

400

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

400

The Lovis 2000 M/ME directly measures

a) Dynamic Viscosity

b) Kinetic Viscosity

c) Both A and B

d) None of the above

D. The Lovis directly measures the ball rolling time and uses the difference between the ball's density and the sample's density to calculate the dynamic viscosity.
400

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

500

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.

500

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.

500

In addition to Pol (ºZ), name two of the three other values measured by the Betalyser.

Sodium

Potassium

Alpha-amino Nitrogen

500

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

500

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.
