For the absolute best quality of knowledge, top quality solvents and reagents are a requirement.

Why is selecting the best grade so important?
Choosing the best grade of chemical or reagent is vital for several reasons. One is that using a low-purity grade can result in low-quality outcomes, with the impression relying on your application and the way sensitive your requirements are. Chelsea Plummer, PhD, senior product advertising manager, chemistry at Waters Corporation, notes that in LC and particularly in LC-MS methods, even small amounts of contamination can decrease sensitivity, leading to incorrect detection limits. “For the highest quality of information, top quality solvents and reagents are a requirement.”

As Plummer explains, “there are two main repercussions and complaints that always stem from choosing the incorrect grade of chemical or reagent.” First, you could end up with complicated results—for instance, a fancy MS spectrum—which makes knowledge evaluation extremely difficult. You may also find yourself taking additional time to troubleshoot, or worse, including downtime to wash your system from the contamination that could be left over when utilizing the incorrect grade of solvents and chemical substances.

Choosing too low a grade can outcome in noncompliance and security issues, particularly in any setting involving food or pharmaceuticals. It can even lead to higher costs due to having to repeat processes or cope with expenses associated to gear injury or substitute. Conversely, using a higher-purity grade than required will lead to greater prices than necessary.

How to choose chemicals and reagents for your functions
When buying chemical compounds and reagents, it’s important to contemplate the meant software, stability price with required purity, and look to regulatory requirements for guidance. Even if you’re not restricted by trade requirements, you could determine that other elements warrant using high-purity reagents. As Plummer notes, as a outcome of excessive price of some lab instruments such as LC-MS methods, getting the most out of the accuracy and sensitivity of these systems must be a priority by using the proper solvents and reagents.

Aside from choosing the right grade, you should also have a look at the intended use for that exact chemical or reagent. For example, within the case of LC-MS, Plummer says using MS-labeled solvents is beneficial as HPLC grade won't be pure enough It’s additionally worth noting that simply checking the label of products just isn't enough, and you also needs to seek the assistance of documentation corresponding to MSDS sheets and certificates of study to verify a product’s suitability on your software.

Choosing too low a grade can end result in noncompliance and safety concerns, notably in any surroundings involving food or prescribed drugs.

Another area to contemplate is benchmarks. If you’re comparing samples to standards, you need to be certain that your chemical substances and reagents are of the identical grade as those used to produce your benchmark samples, and vice versa. Of course, price can be a consideration when purchasing chemical substances and reagents. High-purity merchandise are usually the most expensive and technical grade chemical substances are the cheapest. However, it’s important to keep in mind that you get what you pay for and selecting the wrong grade can result in greater long-term prices.

When it comes to choosing chemical substances and reagents, there’s no one-size-fits-all solution. It’s crucial to think about the meant use, the grade of the product, and the worth earlier than making a purchase.
