World Metrology Day Webinar Series: Measurements for Global Trade 

Calibration and the Making of Medical Devices & Combination Drug Products
Walter Nowocin, Senior Engineering Manager, Metrology & DSR, Medtronic 

Abstract: Calibration plays a critical role in the making of medical devices and combination drug products. In this webinar we will provide the high-level touch points where the U.S. FDA identifies regulatory requirements regarding calibration. We will also review at high-level the important workflows and working environments where and how these products are made; e.g. cleanrooms, packaging, sterilization, and environmental chambers. Various product lines will be used as working examples.

The Critical Role of Pressure Calibration in Clean Room Applications in Regulated Industries
Dallen Baugh, Additel

Abstract: The cleanroom is an essential part of the manufacturing process needed to produce sterile product in highly regulated industries. Cleanrooms must be constantly kept at a higher pressure than their adjacent areas in order to prevent permeation of contaminated air from outside the room. Differential pressure sensors and transmitters are used to monitor and control the cleanroom to the correct positive pressure required. Regular calibrations of these differential pressure sensors is necessary to ensure cleanroom regulatory compliance and ensure a sterile environment. This presentation will discuss challenges and different methods associated with low pressure differential sensor calibrations.

Metrology and the Unsung Hero
Dilip Shah, ASQ-MQD

Abstract: We live in a world where we take everyday events surrounding our lives for granted. The alarm clock gets us out of our beds and the hot beverage awakens our mind. The hot shower freshens our body. On the way to work we fill up our vehicles with gasoline at the gas pump or our electric vehicle has been charged at the home station. What if all the clocks were not synchronized and the temperature of the coffee pots and hot water showers were not consistent, the gas pumps did not deliver consistent volume of gas and the electric chargers did not charge the car batteries fully? All of this involves metrology and the people who maintain systems so goods and services produced give us a form of consistency and comfort. This presentation celebrates 2020 World Metrology Day’s theme of Measurements for global trade by looking at how metrology affects our daily lives. Metrology is transparent until something goes wrong and then we realize how important it is and appreciate the folks who work behind the scenes to make our lives comfortable.
Metrological Traceability of Pesticide Testing in Cannabis
Tim Osborne, A2LA WorkPlace Training 
Abstract: Like any agricultural commodity, Cannabis may be attacked by pests or pathogens and may require treatment with insecticides, acaricides, fungicides, and potentially other crop protection agents (CPAs). Even if none are applied the crop may be grown in soils contaminated by organic chemicals from earlier agricultural operations, exposed to spray drift from adjacent fields, or even take up toxic metals from the soil. Fortunately, many of these types of potential contamination are known in other crops, where tolerance levels are established and monitored through health risk analysis of to assure the safety of vegetable and meat products and beverages. The same approach is used with Cannabis, however there are issues: 1) extrapolation from levels deemed safe for ingestion to inhalation in humans is not always straight forward, 2) cannabis is an extremely complex plant that contains a large variety of chemical compounds, analyzing the cannabis matrix where some of the pesticides may coelute with the measured can make detection and accurate quantification of trace levels of pesticides more challenging. 3) Cannabis is federally illegal so there is no one set tolerances that exist for residue levels on cannabis. Legally defensible analysis depends on traceability; this makes ISO/IEC 17025 accreditation of the laboratory a valuable tool as it helps to set appropriate quality technical requirements to be met for use of a product not well-researched. ISO/IEC 17025 generally requires the use of validated methods, proficiency testing and certified materials. Despite the availability of both ISO 17034-2016 certified and non-certified pesticide reference materials few are sold in a matrix. When there is not a ISO 17034-2016 pesticide infused matrix material available for use as calibrators but a primary reference method is, then there can be a reasonable traceability to the SI, according to the calibration hierarchies addressed in ISO 17511. These meteorological relationships are discussed in the presentation.

Advances with Quantum Hall Effect Resistance Standards
Alireza Panna, NIST
Abstract: Epitaxial graphene based quantized Hall standards have simplified the efforts needed to realize the ohm at the National Institute of Standards and Technology. After giving a brief introduction on the advantages of using epitaxial graphene to realize the ohm rather than traditional GaAs heterostructure based quantized Hall standards, this talk will summarize the recent progress made to realize and advance the ohm through the quantum Hall effect in the following ways: 1) demonstration of a quantum Hall effect Kelvin bridge on a chip to characterize resistance standards 2) realization of a 1 kΩ epitaxial graphene based quantum Hall array resistance standard, and 3) investigation of the quantum anomalous Hall effect as a candidate for next generation quantum Hall standards.
