Frequently Asked Questions (FAQ): PGH Series

This FAQ covers general questions about the PGH series, which are commonly known as high-purity hydrogen generators used primarily in laboratory settings like Gas Chromatography (GC).

Q1: What is a PGH Series Hydrogen Generator?

A PGH series instrument is an electrically powered generator that produces high-purity hydrogen gas through the electrolysis of water. It typically consists of an electrolysis cell, a power supply, pressure control systems, and drying/purification modules to ensure gas quality.

Q2: What are the key technical specifications for a typical PGH unit (e.g., PGH-300)?

While specifications can vary by model, a common reference point is the PGH-300 model:

• Output Purity: ≥ 99.999% (relative oxygen content)

• Output Flow Rate: 0 - 300 ml/min (or as per specific model)

• Output Pressure: 0.4 MPa (approximately 58 psi). Custom pressures can often be requested.

• Power Supply: 220V, 50Hz

• Max Power: 150W

• Operating Environment: Temperature 0-40°C, relative humidity <85%, free from excessive dust and corrosive gases.

Q3: What is the main difference between PGH3, PGH4, and PGH5 series?

The primary difference between these series generally relates to their output flow capacity and potentially advancements in technology. Higher series numbers (e.g., PGH5) likely indicate newer generations designed for higher flow rates, more advanced control systems, or improved efficiency to meet the demands of multiple analytical instruments or high-consumption applications. It's best to consult the manufacturer's specifications for the exact differences between each series model.

Q4: What are the main advantages of using a PGH hydrogen generator?

• Safety: Eliminates the need for high-pressure hydrogen cylinders in the lab.

• Convenience: On-demand, continuous hydrogen production. Simply add deionized water and connect to power.

• Cost-Effective: Lower long-term operational costs compared to purchasing gas cylinders.
