As part of a planned leadership change at IV Labs of Christiansburg, Virginia, Brian Alexander, Ph.D., has been named president of its subsidiary, Inorganic Ventures. The specialty chemical company is a leading manufacturer of certified reference materials (CRM) and analytical inorganic standards trusted by laboratories worldwide.
He succeeds Christopher Gaines, who served as president of Inorganic Ventures and CEO of IV Labs. Gaines moves to board chair, and Justin Yalung has been named CEO of IV Labs.
Alexander, a geochemist, has served as the company's chief technical officer since 2020 and previously as vice president of technical operations. He brings more than a decade of deep scientific leadership to his new role. His promotion reflects Inorganic Ventures' commitment to science-driven growth and its ambition to strengthen its position as the partner of choice for analytical laboratories and manufacturers across the globe.

Gaines moves to board chair, Miller to vice chair, Alexander to president of Inorganic Ventures.
IV Labs, a Christiansburg-based specialty chemistry company serving manufacturers and laboratories worldwide, has appointed Justin Yalung as chief executive officer, and restructured its board of directors to reflect this change, effective June 1.
IV Labs is the parent company of Inorganic Ventures and PURE Laboratories. Together, the companies offer more than 2,000 stock elemental mixtures and compounds and more than 60,000 unique custom formulations. IV Labs products are used for critical production applications, research, testing, and calibration across sectors including pharmaceuticals, energy, environmental safety, mining, industrial manufacturing, and food & beverage.
“At IV Labs, we consider ourselves the quiet force for manufacturers across industries to deliver consistent, high-quality products with confidence,” Yalung said.
Quality Digest recently featured Inorganic Ventures in the article, “Beyond the Pit: Why Laboratory Integrity Now Shapes Mining Viability,” highlighting the growing role analytical accuracy plays in the future of mining operations.
The article examines how mining companies are operating under increasingly narrow economic margins as lower-grade deposits and complex rare earth materials become more common. In these environments, analytical data is no longer just a supporting fun

We’re excited to share that Inorganic Ventures was recently referenced in a Labcompare article exploring the growing importance of laboratory integrity in the mining industry.
When performing elemental analysis most sample preparation and data workup is done in units of µg/g, µg/mL, µg/L, etc. However, when working with pharmaceutical samples the Permitted Daily Exposure (PDE) limits are reported in units of µg/day. Since different pharmaceutical products have different maximum dosages, it is critical to convert the conventional units used by elemental analysts into something that can be equated back to the PDE limit unit of µg/day. The J Value is used to perform this conversion.
If you are testing pharmaceutical samples using USP <232> / <233> and/or ICH Q3D, then you may be familiar with the concept of the J value. The J value is defined below:
PDE limits are determined by USP <232> and ICH Q3D, but the dilution factor and maximum daily dose is determined by you and your sample. The reason that the PDE limit is converted to a J
Poor sample washout or carryover effects can be the cause of inaccurate results when using ICP analysis techniques. Ideally the instrument signal should return to background levels between analyzing samples and standards. Samples
EPA Method 200.8 is an established and widely used ICP-MS method. It describes the analysis of water and wastes for 21 elements. Included in these 21 elements is arsenic, which has a large potential polyatomic interference from 40Ar35Cl. It is common for analysts to face a high bias in their data for 75As. To correct for this potential 40Ar35Cl interference EPA Method 200.8, Table 5, prescribes using the correction equation below:
This correction equation subtracts the counts of 40Ar35Cl from the total counts recorded for mass 75. This is done by measuring the counts from a similar polyatomic: 40Ar37Cl. In theory, the counts for 40Ar35Cl and 40Ar37Cl should be the same
