Detectors

Flow Injection Analysis can utilize a variety of detection types to best analyze different assays. Detection types include colorimetric, fluorometric, amperometric, potentiometric detection, and more. See the FIAlab Methods List below for more information on which assays use which detectors.

Methods List

Colorimetric Detectors

Flame Spectrometer

The Flame spectrometer is built using industry-leading manufacturing techniques that help deliver high thermal stability and low unit-to-unit variation — without compromising the flexibility and configurability that are the hallmark of Ocean Insight miniature spectrometers. New features such as interchangeable slits, indicator LEDs, and simple device connectors deliver more freedom and less frustration.

Ocean Insight Flame Spectrometer

A majority of FIAlab methods utilize colorimetric detection via the Flame spectrometer or low-noise MMS Spectrometer.

tec5 MMS Spectrometer

The MMS module series offers a compact design for detection between 310 to 1100 nm in a variety of wavelength ranges. It combines a high-quality silicon photodiode array with a high-efficiency, imaging-corrected grating. This spectrometer benefits low-level detection limits with its high signal-to-noise and improved sensitivity.

  • FIAlab primarily utilizes the Flame-T-UV-Vis and Flame-T-Vis-NIR models of the Flame Spectrometer series. The spectrometer utilized varies based on the assay(s) you wish to run.

    Models

    Part # 64018 Flame-T-UV-VIS

    Part # Flame-T-VIS-NIR

  • Modular — configurable to your application and needs within the wavelength range 190-1100 nm M

    Compatible — works with all FIAlab light sources, accessories, and software

    Easy to use — plug and play with FIAlab software via the micro USB connection

    User interchangeable slit — allows you to vary the resolution and throughput of the spectrometer on demand

    Indicator LEDs — indicator of power and data transfer status at all times

    Compact and lightweight — small size and no moving parts makes it ideal for integrating with portable systems and demanding environments

    Low Power Consumption - drawing <250mA at 5V, the Flame-NIR can be powered almost anywhere including in OEM portable and handheld devices and industrial process control environments.

Fluorometric Detection

Fluorometric detection is used in FIAlab’s EPA approved method for Ammonia and TKN analysis via OPA indicator.

PMT-FL Photomultiplier

PMT-FL

The PMT-FL Fluorometer is an ultra-sensitive, photomultiplier-based detection system designed for monitoring very low fluorescence, chemiluminescence, or bioluminescence emissions. The heavy-duty housing is chemically resistant and built to withstand industrial environments.

  • PMT-based ultra sensitivity fluorescence/chemiluminescence detector

    The PMT- FL accepts either a flow through or a conventional quartz cuvette for manual sample handling. The detection limit is guaranteed to be 10 parts per trillion - obtained with Fluorescein @ 250 msec integration time and appropriate emission and excitation filters.

    This product is compatible with all FIAlab's analyzers or with a mini peristaltic pump for manual operation. LEDs from 270 nm to 920 nm are available.

    Part # 77035

  • High Sensitivity Fluorescence Measurement

    PMT Specifications: Photon counting PMT detector 310 nm - 750 nm spectral range.

    Pulse pair resolution: 10 ns responsivity @ 400 nm: 5 X 1017 cps/Watt PMT dynamic range: 2.0E06

    The PMT-FL is built to order with either an internal excitation lamp or an SMA-terminated fiber optic cable for use with an external lamp. Emission and excitation filters are mounted in user-accessible slots inside the enclosure, allowing for quick removal or exchange.

    Additional Components:

    Built-in bandpass excitation and/or emission filters. We offer numerous bandpass filters for fluorometric assays. These range from the UV through VIS.

Amperometric Detection

Amperometric Flow Cell and Electrode

Amperometric analysis is a highly sensitive detection technique applicable to redox-active analytes. The sample is brought in contact with an electrode that oxidizes/reduces the analyte, giving rise to an electric current proportionate to the concentration.

Amperometric detectors are an alternative to colorimetric detection for Cyanide determination.

Flame Photometric Detection

Flame Photometer

Photometric analysis entails directing the sample solution to a burner flame and measuring the characteristic color that ensues in the presence of metal ions. The technique is applicable to alkali and earth alkali metals.

Potentiometric Detection

Ion-Selective Electrode

Potentiometric analysis utilizes ion-selective electrodes that develop an electric potential in response to the ionic analyte that the electrode is specific for.
