We’ve all been there: You’re eager to carry out a straightforward Flash purification. Easy, right?
But then reality hits. You start prepping your reaction mixture, pondering how to monitor the reaction, verify the product, and develop your Flash method... Suddenly, what seemed like a simple task turns into a half-day adventure filled with sample prep and endless scrolling through social media while waiting for your LC/MS results.
This post will guide you through some innovative ways to make Flash purification smoother and more efficient than ever before. We’ll cover tips for reaction monitoring, purification, and fraction identification.

### 1. Pre-Flash Run: Monitoring Your Reaction
Before you even touch the Flash system, you face critical decisions that could save—or waste—hours of your day. One key choice is how to efficiently confirm whether your compound has formed.
#### Tip #1: Choose the Fastest Monitoring Method
While LC/MS is often considered the gold standard, it’s not always the fastest or most convenient option. Consider alternative methods like TLC (Thin Layer Chromatography), which can provide quick answers to whether your reaction worked. Look for the simplest, most accessible technology in your lab to get the job done swiftly.
#### Tip #2: Streamline Sample Preparation
If you opt for TLC over LC/MS, you’ll still need to scrape spots and prepare samples for injection. Here’s where tools like the TLC Plate Reader can step in. These modern devices allow for push-button analysis, eliminating the hassle of manual preparation and cleanup.

### 2. During the Flash Run: Leveraging Automation
Thankfully, technology is increasingly on our side. Advances in AI and automation mean many tedious tasks, including Flash method development, can now be simplified.
#### Tip #3: Simplify Flash Method Development
Developing a Flash method involves multiple variables—Rf values, column selection, and more. If your Flash system offers AI-driven suggestions, take advantage of these features. For example, our app “TLC to Flash & Prep Chromatography†lets you snap a photo of your TLC plate, automatically detects compounds, and transfers relevant data directly to your puriFlash® system.
Additionally, the Intersoft X software uses embedded intelligence to recommend the optimal method and column for your purification. Even if your ideal column isn’t in stock, the software adapts seamlessly.

### 3. After the Flash Run: Identifying Fractions
Once your purification is complete, you’ll want to ensure accurate fraction identification without resorting to LC/MS.
#### Tip #4: Simplify Fraction Identification
There’s no single best method for identifying compounds. While TLC is great for reaction monitoring, consider tools like the Advion ASAP® probe for rapid fraction ID. Simply dip the probe into your tube and insert it into the APCI ion source of the CMS expression® mass spectrometer for prep-free sampling.
#### Tip #5: Collect by Mass
Traditional detectors like UV and DEDL only signal the presence of compounds but lack specificity. Adding a mass spectrometer as a complementary detector enables you to identify compounds based on their m/z ratios. Coupling a puriFlash system with the CMS expression® mass spectrometer allows for targeted collection of your desired compounds.

### Final Thoughts
From reaction monitoring to fraction identification, Flash purification doesn’t have to be a complex ordeal. By leveraging advanced tools like TLC Plate Readers, automated software, and mass spectrometry, you can streamline every step of the process.
