TLC Report — A comprehensive digital solution for pharmaceutical testing laboratories, research institutes, and analytical chemistry laboratories in thin-layer chromatography (TLC) imaging, processing, and documentation.
🔬 KEY FEATURES:
1. Professional Chromatography Image Processing (OpenCV Native):
• Perspective Transform: Completely eliminates distortion and tilting when capturing thin layers with a smartphone camera.
• Adaptive Local Contrast Enhancement (CLAHE): Clarifys blurry areas and hard-to-see chromatographic spots.
• Gamma Correction & Display Filters: Fine-tune brightness and color saturation to clearly identify the color of test spots without distorting the original image data.
• Automatic EXIF Processing: Recognizes and correctly rotates the camera-captured image upon loading.
2. Interactive Marking & Accurate Rf Index Calculation:
• Automatic zoom (Auto-fit) and full view of the thin layer immediately upon image opening.
• Intuitive touch operation to set Baseline, Solvent front, test/standard samples, and sample identification labels.
• Supports smooth drag-and-drop fine-tuning, D-pad tool for pixel-by-pixel coordinate adjustment (±1 px).
• Convenient multi-step undo history.
• Automatically calculates instant Rf values using the standard Pharmacopoeia formula with standard Vietnamese decimal point format (e.g., 0.50; 0.72).
3. Parallel Comparison of Two Blocks (Block A / Block B):
• Flexible management of two thin layer strips in the same work session (comparing test samples and standard samples of medicinal materials).
• Automatically synchronizes spot numbers and Rf values to the detailed data table.
• Integrated keyboard with quick access to specialized characters: °C, μ, μg, μL, λ, α, β, γ.
4. Export Standard A4 PDF Reports:
• Professional A4 layout, completely consistent between mobile and desktop versions.
• Embed sharp images of biomarkers with clear markers and label symbols.
• Integrated Vietnamese font with full and sharp diacritics.
• Supports PDF preview, direct printing, saving to device memory, or quick sharing via Email or Zalo.
5. Completely Offline Operation:
• All image processing and PDF creation algorithms run directly on the device (On-Device).
• No images or test data are sent to external servers, ensuring the safety and security of test report information.
6. Completely Ad-Free & Support the Author:
• 100% clean app, free from any banners, pop-ups, or video ads that interrupt your work.
• Includes a voluntary In-App Purchase feature to "Support the Author" to help fund the app's maintenance and development.
Process thin-layer chromatography images, align angles, calculate Rf values, and export a standard A4 PDF report.
