Patricia Atkins, Product Application Scientist at SPEX CertiPrep, participated in the Stakeholder Panel on Strategic Food Analytical Methods (SPSFAM) “Cannabis Potency” Working Group. The group worked to develop Standard Method Performance Requirements (SMPRs®) in an effort to find fit-for-purpose method(s) for cannabis potency. The working group examined analytical challenges, regulatory requirements, and gaps in current methodology, etc. to submit SMPRs against which candidate methods can be evaluated. The SMPRs that are developed will be applicable for industry and regulators alike. The AOAC stakeholder panel, SPSFAM, will be used to advance draft standards developed by this new working group.
The group narrowed its focus to five cannabinoids (of the 15 compounds of interest) required for the initial SMPR; THC, THCA, CBD, CBDA, and CBN. Draft SMPRs were developed and are posted on the AOAC website at SPSFAm SMPRs for Public Comment: Cannabis and Proanthocyanadins in Cranberries and is open for public comment.
The standards development activities for cannabis potency are supported by AOAC Organizational Affiliates (OA) companies SPEX CertiPrep, Sigma-Aldrich, GW Pharmaceuticals, SCIEX, CEM Corp., and SC Labs through AOAC’s working group initiative.
The AOAC Official Methods Board recognizes significant contributions and meritorious volunteer service to the AOAC analytical scientific community. Awards for both team and individual service are reviewed annually by the Official Methods Board. Award categories are: Achievement for Technical and Scientific Excellence, Expert Review Panel of the Year, Method of the Year, and Technical Service Award. Awardees receive their recognition during the AOAC Awards Ceremony during the AOAC Annual Meeting.

On Monday, August 21, 2017 there will be a solar eclipse across the United States. Now why is this eclipse special you ask… this is the first time since 1880 that a total solar eclipse will occur exclusively over the United States. No other country will see totality, though many countries will see a partial eclipse of the sun.2 The eclipse will take about 90 minutes to cross the United States and pass through about 12 states.3
So what exactly is a total solar eclipse? A total solar eclipse occurs when the Moon completely blocks the solar disk. In a total solar eclipse, the narrowest part of the path (where the Sun is completely blocked and the Moon casts its darkest shadow, called the umbra) is called the “zone of totality”.
What are the scientific benefits of the eclipse? The total solar eclipse offers scientists a unique opportunity to pursue a number of unique science and engineering problems. The very dark color of the moon can be used to calibrate X-ray imagers to properly record the ‘zero signal’ state, while the eclipse will block out the disk of the sun letting the light from the mysterious inner corona within 100 km of the solar photosphere shine into various experiments for detailed study.1
Fun Fact! If you are one of the lucky ones in the totality zone, you may see stars in the daytime! As the sky darkens, planets and stars hidden in the sky by the Sun’s bright light will reappear. Look for Mars, Mercury, Jupiter, and Venus during totality.2
View the Eclipse with SPEX CertiPrep
SPEX CertiPrep would like to help you view the eclipse with us! All U.S. web orders placed on August 14th through August 18th will receive a pair of eclipse glasses for your viewing pleasure.

National Lipstick Day is on July 29th, 2017. In honor of National Lipstick Day, SPEX CertiPrep would like to share our App Note
Analysis of Lipstick for Toxic Elements using ICP-MS
Evidence of the use of cosmetics, including lipstick, has been found in civilizations as early as ancient Mesopotamia. Many of the cosmetics used throughout history have contained potentially toxic elements and other contaminants. Ancient Egyptians used cosmetics containing large amounts of lead and mercury. Modern cosmetics are perceived to be free of dangerous toxins due to widespread regulation of many consumer products. The FDA, which oversees the regulation of cosmetic products, does not have regulations governing the level of toxic or dangerous contaminants in finished products, such as lipsticks. The FDA regulates limits on compound concentrations of additives and colorants, but no overall regulation is in place for the finished product’s level of potential contamination.
Studies prior to 2012 have found levels of lead up to 3 ppm in lipstick. The purpose of this study was to re-examine the potential for lead contamination in lipstick and determine if any other potentially toxic metals were present in these lipsticks. 48 lip products including lipsticks, lip glosses, moisturizing sticks, and lip stains were tested for the presence of toxic elements by ICP-MS.
Fun Facts About Lipstick
The first manmade lipsticks appeared around four to five thousand years ago in Ancient Mesopotamia
Some civilizations did not allow women to appear in public without extensive facial makeup.
80% of American women regularly wear lipstick, and over 25% won’t leave the house without wearing it.
Lipsticks can contain fish scales and castor oil that provides lips with a shiny film that can’t be smeared easily.
The most famous actresses that popularized lipsticks were Greta Garbo, Joan Crawford, Marilyn Monroe and Elizabeth Taylor

Speciation In Our World
In this issue we discuss the importance of arsenic speciation in rice products and a case study for methylmercury poisoning in Japan.
IN THIS ISSUE:
An In-Depth Look at the Importance of Arsenic Speciation in Rice Products
ABSTRACT: Rice is an agricultural commodity of high economic and nutritional importance around the world. Rice is a staple for nearly half of the world’s seven billion people with between 500 – 8000 million metric tons consumed each year. Rice consists as a staple in more than 80% of Asian diets. In recent years, there have been ongoing studies pointing to high levels of natural arsenic accumulation in rice. Rice is unique among the grains to exhibit this kind of contamination and the reasons for it are as interesting as they are necessary to understand in order to ensure a safe food supply. Take a look at our article on rice and arsenic species in this issue!
A Case of Methylmercury Poisoning
ABSTRACT: Mercury is a common environmental and aquatic contaminant this found as both natural chemical by-products and persistent pollutants from agricultural and industrial processes. In the 1940’s and 1950’s, Japanese citizens were plagued by mysterious neurological symptoms which later would be linked to industrial chemical manufacturing discharges into bays and rivers. Our article on a historical methyl mercury poisoning event is featured in this issue’s discussion of speciation in our world.

Flag Day honors the resolution from the Second Continental Congress on June 14, 1777 which called for an official United States Flag
Here are some interesting facts about Flag Day and the American Flag
- Flag Day is not a federal holiday, however, it is a state holiday in Pennsylvania
- The colors of the American Flag are quite significant
- Red symbolizes hardiness and valor
- White symbolizes purity and innocence
- Blue symbolizes vigilance, perseverance and justice
- For a while the U.S. added stars and stripes to the flag when welcoming new states. As the country continued to add new states, the U.S. decided to go back to 13 stripes to represent the original 13 colonies
- A local Philadelphia seamstress, Betsy Ross, sewed the original United States flag
- Why stars and stripes? Stars are considered a symbol of the heavens and the divine goal to which man has aspired from time immemorial; the stripe is symbolic of the rays of light emanating from the sun

Analytical Standards for Single & Dual Speciation Analysis
Speciation analysis has become common in many testing fields, including in the environmental, food and pharmaceutical testing labs. To analyze species in a sample requires Certified Reference Materials (CRMs) for sample verification and method validation.
SPEX CertiPrep offers a wide variety of speciation standards, certified to the strictest ISO Guide 34 guidelines and tested on our own LC-ICP-MS.
Single and Multi-Element Speciation Standards include Arsenic (+3), Arsenic (+5), Chromium (+3), Chromium (+6), Selenium (+4), and Selenium (+6).
What is speciation analysis?
The International Union of Pure and Applied Chemistry (IUPAC) defines speciation as ‘the distribution of an element amongst defined chemical species in a system’. Speciation analysis is the analytical process of identifying and/or measuring the amounts of one or more individual chemical species in a sample.
