miniTOC

Product catalog summary

Overview: The miniTOC is a monitoring device designed for online and offline control of total organic carbon (TOC) in pure and ultra-pure water. It utilizes a high-speed flow-through concept with direct surface UV oxidation and conductivity detection to ensure fast and accurate monitoring.

Technical Specifications:

Method & Detection: UV oxidation and conductivity.
Sample Volume Flow: Approximately 14 mL/min.
Measurement Period: 2 seconds (online mode), 1 minute + 5 minutes purging (offline mode).
Measurement Range: 0.5 to 1000 ppb.
Detection Accuracy: Less than 50 ppb ± 0.5 ppb, greater than 50 ppb ± 1%.
Ports: Basic configuration includes 1 sample port and 1 SST port; Pro configuration includes 1 sample port and 3 SST ports.
Related Norms: USP <643>, EP 2.2.44, DIN EN 1484.
Ambient Parameters: Relative humidity 10 to 95%, temperature 10 to 45°C.
Interface Ports: Analog (0 - 20 mA), compliant with Namur NE43.
Dimensions, Weight, Power: 300 x 200 x 500 mm, 14 kg, 110 - 230 V, 50 Hz, 60 Watt.

Sample Requirements:

Type of Sample: Pure to ultra-pure water.
Sample Input Conductivity: Less than 2 µS/cm (upgradable to less than 10 µS/cm).
Inlet Pressure: Less than 0.5 bar (pressure reducer needed if higher), optional 0.25 bar.
Sample Temperature: Less than 50°C.

Configurations and Options:

The miniTOC can be configured with up to 4 inputs and upgraded with software to measure up to 3 loops sequentially.
An offline configuration is available with an autosampler for 15 positions of 100 mL vials.
If medium pressure exceeds 1 bar, a pressure transducer is required.
If medium temperature exceeds 50°C, a heat exchanger is required.
Housing is IP54 rated for protection against dust and water jets.
Software is compliant with 21 CFR part 11 for pharmaceutical applications.
Includes a sample flow check that initiates an alarm if inlet flow is zero, in combination with a pressure sensor.

Consumables:

UV reactor, tubes for peristaltic pump, calibration solution, SST Kit, documents for IQ/OQ/PQ, 100 mL vials, and septa for vials are available as consumables.

The miniTOC system is designed for total organic carbon (TOC) online/oﬄine monitoring of pure and ultra pure water. The miniTOC monitoring device uses the high speed ﬂow through concept and the efﬁcient „direct surface“ UV oxidation. In combination with conductivity detection the miniTOC guarantees a fast monitoring of values. By measuring the conductivity before and after the UV oxidation the TOC value can be cal
