Title: Measurement Uncertainty Its NELAC How Do You Approach It
Description: Measurements are made to:
· Accept or reject a product
· Determine if an instrument is running properly
· Assess the value of a product or service
There is always some unknown error associated with every measurement. The quantity of this unknown error can be defined as measurement uncertainty.
To determine the quality of a measured value an estimate of measurement uncertainty, which determines the confidence of measurement must be given.

Title: Quantification of Measurement Uncertainties of Reference Materials by SPEX CertiPrep
Description: An evaluation of the total combined uncertainties of a reference material manufactured by SPEX CertiPrep is provided in the presentation below. Erbium, prepared to give a target value of 1000 mg/L is chosen as an example. High purity Erbium Oxide (Er2O3) which was assayed for Erbium by EDTA titration and trace impurities determined by ICP/ICPMS, was weighed accurately and then dissolved in high pure nitric acid. Erbium concentration in the solution was determined first by wet assay and then by ICP.

Title: Calibration Strategies and Dilution Practices
Description: We have observed over the years that chemists use a variety of techniques to dilute solutions and calibrate instruments. We have also observed that many techniques in common practice contain an unacceptable amount of error and uncertainty. We wish to promote good laboratory practices and reduce the errors at the bench. The goal is to show calculations, uncertainties and lab practices that will help chemists make better measurements, or understand why they do so well.

| Are the Uranium standards natural or depleted? What are the isotopes for Uranium and Thorium?
| | | Uranium is depleted. 99.777% U-238; 0.2213% U-235; 0.00089% U-234. The Thorium standards are 100% Th-232. |
| When calculating gravimetric factors for Ion Chromatography standards, remember that:
| | | 1000 ug/mL Nitrate = 226 ug/mL Nitrogen
1000 ug/mL Phosphate = 326 ug/mL Phosphorus
1000 ug/mL Nitrate-Nitrogen = 1000 ug/mL Nitrogen
1000 ug/mL Phosphate Phosphorus = 1000 ug/mL Phosphorus
1000 ug/mL Nitrate = 305 ug/mL Nitrogen
1000 ug/mL Sulfate = 334 ug/mL Sulfur
1000 ug/mL Nitrite Nitrogen = 1000 ug/mL Nitrogen
1000 ug/mL Sulfate-Sulfur = 1000 ug/mL Sulfur

| Are your standards traceable to NIST?
| | | Yes. Unlike many manufacturers, every standard we manufacture is directly traceable to a NIST SRM (where available). |
| Is there a minimum volume for a custom standard?
| | | We now supply inorganic custom standards in 100 ml, 250 ml, 500 ml and 1 Liter volumes. Organic standards are supplied in 1.2ml or 5.2ml ampule sizes. |
| Acid Still Frequently Asked Questions
| | | Q: What are the dimensions of the Acid Still?
A: 27Wx27D60H (cm) (from Massen booklet)
Q: How much acid is necessary to run?
A: Minimum: 150 mL and that amount has to be watched carefully so it doesn't evaporate to dryness.
Maximum: 750mL to 800 mL
Q: Are there any temperature requirements?
A: We use the maximum wattage 100 W
Q: How long does it takeand how much acid is made?
A: 1.2 l per 24 hour
Q: Are there fume hood requirements?
A: You have to check with your labor laws. But we recommend it. |

| How do I prevent my antimony oxide (Sb2O3) solution from becoming a gelatin when I dissolve it in tartaric acid? SPEX CertiPrep Laboratory Manager Vanaja Sivakumar says, "This is a great question with a very easy solution. While Sb2O3 dissolves easily in tartaric acid and water, the solution is clear at first but a gelatin like substance can form over time. This is a form of mold. Adding a trace amount of nitric acid to the solution can prevent this. Thanks for asking." |

| Can you please provide some tips on calculating gravimetric factors for Ion Chromatography Standards?
Great question, here are examples based on the most popular IC Standards we offer:
1000 ug/mL Nitrate = 226 ug/mL Nitrogen
1000 ug/mL Phosphate = 326 ug/mL Phosphorus
1000 ug/mL Nitrate-Nitrogen = 1000 ug/mL Nitrogen
1000 ug/mL Phosphate-Phosphorus = 1000 ug/mL Phosphorus
1000 ug/mL Nitrate = 305 ug/mL Nitrogen 1
1000 ug/mL Sulfate = 334 ug/mL Sulfur
1000 ug/mL Nitrite-Nitrogen = 1000 ug/mL Nitrogen
1000 ug/mL Sulfate-Sulfur = 1000 ug/mL Sulfur |

| Why should the acid concentration in the sample be similar to the standard it is measured against?
The density, viscosity and surface tension of the matrix have considerable effect on the droplet size of the aerosol. Only fine droplets are transported to the plasma torch. Matching the acid concentration of the sample and the standard helps in transporting similar quantity of droplets (from both the solutions) to the torch thus improving the accuracy. |

| Welcome to the first issue of the SPEX SamplePrep Tech Corner. SPEX SamplePrep, LLC is dedicated to sample preparation and handling. Our focus is the analytical laboratory and process control laboratory, and we have also expanded into R&D labs with innovative instruments like our cryogenic grinding systems.
The technical flavor in this section of our website reflects the needs of our customers as they are presented to us, and provides examples of and insight into many of the problems that confront analytical spectroscopists
If you have a particular request that can be addressed in the Tech Corner, please e-mail us or call SPEX Sample Prep at 1-800 522-7739 X 450. We are always interested in new challenges in the world of sample preparation.
SPEX SamplePrep was founded in 1954 to provide superior analytical equipment for spectroscopy applications. A major area of spectroscopy that is dependent on grinding methods is X-ray Fluorescence (XRF). Since the very beginning, our mission has been to provide spectroscopists with quality products backed by service and expertise.
Regardless of the sophistication of your analytical equipment, your data can be useless if the sample is not representative or is badly prepared.
Grinding Studies for X-ray Fluorescence (XRF) methods (Powders) All X-ray spectrometers require the following for accurate and reproducible results:
- That the sample is flat.
- That the sample is homogeneous.
- That the particle size is consistent and small (1 to 10 micron).
All of these are not always easy to achieve, and if a sample has pronounced mineralogy effects it may have to be evaluated on an individual basis##! |
