In-house N
2
gas supply used as the
main N
2
source.
Pressurized N
2
Gas:
• N
2
content: > 95% by volume
• Dew point: < -60°C @ 1 bar
• Pressure: 6-10 bar
• Oil content: < 0.005 ppm (0.00425 mg/m
3
)
• Solid impurities: Use 5 micron filters, filters
should retain 99.99% of the specified particles.
Capacity:
• Prodigy Unit: 40 l/min. (1.4 cfm) + VT gas: 11
l/min. (0.4 cfm).
• Sample protection option: Add 40 l/min. (1.4
cfm) to above values.
Case 2:
Compressed air with dew point <
-25°C available.
Use an N
2
gas separator to generate the required
N
2
gas on site (as specified in Case 1). Bruker
offers a N
2
Separator (P/N 46540). Requirements
for compressed air:
• Pressure: 7-10 bar.
• Oil content: < 0.005 ppm (0.00425 mg/m

)
• Solid impurities: Use 5 micron filters, filters
should retain 99.99% of the specified particles.
• Capacity: > 200 l/min. (7 cfm).
Case 3:
Compressed air with dew point >
-25°C available.
Use an additional air dryer in order to obtain
compressed air with a dew point < -25°C @ 1 bar
(as specified in Case 2 above). Bruker offers a
membrane dryer with 60 l/min., -80°C (P/N
1808577).
Backup N

Independent N
2
gas source, e.g. a N
2
gas cylinder
fitted with a pressure reducing value.
Specifications: See Case 1 above.
