Meet the FRACTION FINDER ULTRA, featuring a brand new, ultra-sensitive sensor.

Typically ships in 3-5 business days.

The FRACTION FINDER ULTRA is Arometrix’s real-time molecular monitoring system for botanical processing. This new model serves new processes that require extreme detection, such as Chromatography, as well as all processes that the original FRACTION FINDER can be used for (short path, wiped film and thin film distillation).

This patent-pending technology is essential for getting the purest, most consistent product possible. Forget the old ways of relying on experience, guesswork, and eyesight alone – now you can increase your potency with this unique approach to real-time molecular tracking.


Features & Details

The (Ultra-Sensitive) Sensor

  • Uniquely built to attach directly to chromatography glassware, our GL18 Chroma Adapter, or another adapter/sight glass in seconds
  • Connects and transmits to the pole-mounted, high-quality display
  • Plug and play – instantaneously analyzes the mixture flowing through the processing machine
  • Available in size 34 (fits 31-34mm OD glass)
  • The ultra-sensitive sensor has a new filter that allows it to be significantly more sensitive than our standard FRACTION FINDER

The Digital Display

  • Tablet-sized display mounts directly onto a lab pole
  • Connects and interprets the wavelength information from the sensor
  • Touch-screen interface displays real-time molecular information about the contents of your fraction/solution throughout the process
  • Compatible with all Arometrix sensor technology

The High-Quality Software

  • Molecular Selection – Select from a growing list of key molecules, including CBD; see full list here
  • Intensity Values – Track as molecular intensity levels increase and decrease throughout the process
  • Data Logging – Record and export run data for traceability
  • Software Updates – Upgrade to software releases easily from the field (currently V1.2.3)

Why did we create this ultra-sensitive sensor?

For certain processes, such as Chromatography, highly sensitive tracking of individual molecules is essential. This is because these processes involve high amounts of solvent. The more solvent used, the more senssitive the detection needs to be.

The ULTRA sensor contains a detector with an improved Lower Detection Limit, allowing users to track key molecules through high amounts of solvent AND better distinguish similar molecular signals.

NOTE: If you are an existing customer, you have the option to buy or upgrade to a standalone Ultra-Sensitive Sensor.

Lack of inexpensive, easy fraction monitoring during chromatography

Chromatography is a challenging process that requires experimentation to get right. During the process, it can be challenging to time fraction changes for precise separation, let alone do it precisely and consistently.

It is common for Chromatography operators to look to pair their columns with on-site analytics. However, this can be incredibly expensive. Additionally, most Chromatography processes don’t use UV detection as a gross source of flow data; rather; they extend the process with a long, thin tube where multiple sensors provide UV data readings.

Arometrix’s solution is a more affordable, easier alternative. Not only can the system provide real-time, in-line data during Chromatography, but it can also be easily removed and then used during fractional distillation processes.

Application: Chromatography Process Monitoring

Arometrix’s disruptive solution is the patent-pending FRACTION FINDER ULTRA. Processors refer to it while they are operating to view molecular levels and changes. By using the system in tandem with existing laboratory and processing techniques, you’ll have a wealth of additional information on which to base decisions.

For example, the data will let you easily monitor fraction peaks to know when to stop eluting, switch fractions, or switch columns. Knowing exactly when each fraction starts helps you with precise and repeatable separation of fractions.

Additionally, this technology is great for rapidly training novice technicians on the process, or standardizing processes across a large facility.

Applicable processes for this model include:

  • Normal-phase chromatography
  • Reverse-phase chromatography
  • Color remediation chromatography
Powered by fluorescence spectroscopy

Arometrix’s technology utilizes a principle known as fluorescence spectroscopy, a branch of science concerned with measuring molecules based on how they interact with light. The system uses a spectrum of wavelengths over time to determine the relative purity of oils flowing through a glass condenser or sight glass. This technique paves the way for precision and repeatability, which will yield a more consistent product over time.

Product Details


What’s the difference between the ULTRA sensor and the original sensor?

The original sensor is used for distillation (e.g. short path, wiped film, thin film). It is available in two sizes: size 29 and size 34.

The new ULTRA sensor is used for distillation PLUS chromatography and conversion reactions. It is available in one size only: size 34. Specifically, it has an ultra-sensitive detector, new magnetic locking mechanism, anodized aluminum apertures, and a re-oriented sensor strap.

Does the Ultra sensor require a different display and/or software than the original sensor?

Currently, no; all of our sensors use our same digital display and software.

Can this be used for pesticide detection?

No, this system can NOT be used for pesticide detection.
