We've all been there: you're ready to do a straightforward Flash purification. Easy, right? But then you start thinking about preparing your reaction mixture, keeping an eye on the reaction progress, confirming your product, and setting up the Flash method. These steps can easily turn into hours of work and waiting around for LC/MS results.
This post shares some practical tips to make Flash purification smoother than ever. We’ll cover how to streamline reaction monitoring, simplify method development, and identify your purified fractions without unnecessary hassle.

**1. Preparing for the Flash Run: Monitoring Your Reaction**
When you’re getting started, you face a few key decisions. First, figure out the quickest and simplest way to confirm whether your compound has formed. Many people immediately reach for LC/MS, but consider using TLC instead. TLC is often faster, cheaper, and just as effective for checking if your reaction worked.
**Tip #1: Optimize Reaction Monitoring**
Instead of waiting for LC/MS results, try TLC. It’s less time-consuming and doesn’t require complicated sample preparation. Simply run your TLC plate and check if your compound appears. This method lets you get answers quickly and move forward without delay.
**Tip #2: Skip the Fuss with Sample Prep**
If you opt for TLC over LC/MS, you’ll still need to prepare your samples. Traditionally, this involves scraping spots off the plate and dissolving them for analysis. However, modern tools like the TLC Plate Reader eliminate this step entirely. Push a button, get instant results, and avoid the tedious prep work.

**2. During the Flash Run: Streamlining Method Development**
Once you’ve confirmed your reaction, it’s time to set up the Flash system. Developing a purification method can seem daunting, especially if you’re new to Flash chromatography. But today’s advanced technology makes this process easier than ever.
**Tip #3: Simplify Method Development with AI Assistance**
Many modern Flash systems come equipped with AI-driven tools that suggest ideal conditions for your purification. All you need to do is take a picture of your TLC plate, upload it to the system, and let the software recommend the best column and method parameters. For example, our app “TLC to Flash & Prep Chromatography†automates this process by detecting compounds, analyzing solvents, and transferring data directly to the puriFlash® system.
The Intersoft X software takes it a step further by offering real-time guidance, ensuring your purification runs smoothly every time—even if you don’t have the exact column in stock. The system adapts seamlessly to your setup.

**3. After the Flash Run: Identifying Fractions**
Your purification is complete, and you’ve collected your fractions. Now comes the task of identifying which tubes contain your desired compound. Traditionally, people turn back to LC/MS, but there are smarter ways to achieve this without the extra effort.
**Tip #4: Use Direct Sampling for Fraction Identification**
For a faster, simpler solution, consider using the Advion ASAP® liquid/solid probe. Simply dip the probe into your fraction tube and insert it into the APCI ion source of the CMS expression® mass spectrometer. This allows you to analyze samples without any prep work—no LC/MS required.
**Tip #5: Collect Compounds Based on Mass**
To take identification to the next level, combine your Flash system with a mass spectrometer. Unlike UV or DEDL detectors, which only show compound presence, a mass spectrometer provides detailed information about each compound’s m/z ratio. This lets you directly collect fractions based on their mass, ensuring precision and accuracy.
