Why is choosing the proper grade so important?
Choosing the best grade of chemical or reagent is vital for a quantity of causes. One is that utilizing a low-purity grade can lead to low-quality results, with the impact relying on your application and the way delicate your requirements are. Chelsea Plummer, PhD, senior product advertising supervisor, chemistry at Waters Corporation, notes that in LC and particularly in LC-MS strategies, even small amounts of contamination can lower sensitivity, resulting in incorrect detection limits. “For the highest quality of information, high quality solvents and reagents are a requirement.”

As Plummer explains, “there are two main repercussions and complaints that usually stem from choosing the incorrect grade of chemical or reagent.” First, you would end up with complicated results—for instance, a complex MS spectrum—which makes information analysis extremely challenging. You may additionally end up taking additional time to troubleshoot, or worse, adding downtime to clean your system from the contamination that can be left over when utilizing the mistaken grade of solvents and chemicals.

Choosing too low a grade can lead to noncompliance and security issues, notably in any environment involving meals or prescription drugs. It can even result in greater costs because of having to repeat processes or deal with bills related to tools damage or replacement. Conversely, utilizing a higher-purity grade than required will lead to higher costs than necessary.

How to choose on chemicals and reagents in your applications
When purchasing chemical substances and reagents, it’s essential to consider the supposed software, steadiness value with required purity, and look to regulatory requirements for steerage. Even if you’re not restricted by trade standards, you could determine that other components warrant the use of high-purity reagents. As Plummer notes, as a result of high value of some lab devices similar to LC-MS methods, getting the most out of the accuracy and sensitivity of those techniques must be a precedence by utilizing the best solvents and reagents.

Aside from choosing the right grade, you should also take a look at the meant use for that specific chemical or reagent. For instance, within the case of LC-MS, Plummer says utilizing MS-labeled solvents is beneficial as HPLC grade won't be pure sufficient It’s additionally worth noting that simply checking the label of merchandise is not enough, and also you also needs to seek the assistance of documentation similar to MSDS sheets and certificates of study  to substantiate a product’s suitability for your utility.

Choosing too low a grade can result in noncompliance and safety concerns, significantly in any setting involving food or pharmaceuticals.

Another space to contemplate is benchmarks. If you’re evaluating samples to requirements, you should make positive that your chemical substances and reagents are of the same grade as those used to produce your benchmark samples, and vice versa. Of course, price is also a consideration when buying chemical compounds and reagents. High-purity merchandise are usually the costliest and technical grade chemical substances are the cheapest. However, it’s essential to keep in mind that you get what you pay for and choosing the mistaken grade can result in larger long-term prices.

When it comes to selecting chemical compounds and reagents, there’s no one-size-fits-all resolution. It’s essential to consider the meant use, the grade of the product, and the value earlier than making a purchase order.
