New Names for Acetonitrile and Methanol in Liquid Chromatography: Greater Clarity and Improved Performance
3' tempo di lettura
At CARLO ERBA Reagents, clarity is just as important to us as the quality of our reagents.
That’s why, starting in 2026, we are evolving the names of our grades to better reflect their intended uses.
Out with the historical designations—welcome a simpler, clearer, and fully consistent nomenclature, designed to help you quickly identify the grade best suited to your needs.
🔄 A gradual rollout throughout 2026
The transformation begins as early as April 2026, with a first wave of products: acetonitrile and methanol references for liquid chromatography.
👀 You may have already noticed these new labels on our packaging:
ACCESS – HPLC, LAB – High Gradient, EXPERT – LC‑MS, or PREMIUM – UHPLC‑MS
➡️ Only the names are changing: the quality, reliability, and trust remain exactly the same.
 | ACCESS – HPLC conforms ACS gradient | For your routine analysis | |
 | LAB – HPLC High Gradient | For your advanced Gradient elution applications | |
 | EXPERT – LC-MS, far UV | For your complex matrices and UHPLC needs | |
 | PREMIUM – UHPLC MS | For your very complex matrices and High-Resolution UHPLC needs |
✅ What’s changing:
- New grade names aligned with the intended uses of our products
- Improved specifications for the LAB – High Gradient range
- RS – Gold is gradually being phased out in favor of LAB – HPLC High Gradient and EXPERT – LC‑MS, far UV, depending on your analytical needs
✅ What’s not changing:
- The CARLO ERBA Reagents quality
- Our manufacturing standards
- Our chromatographic expertise
- And above all, your product codes remain the same!
